SUMMARY:Speaker: Cameron Geddes (LBL Accelerator Division) - Title: Accelerators for Future Colliders
DESCRIPTION:Research Progress Meeting \nDate: March 7\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Cameron Geddes (LBL Accelerator Division) \nTitle: Accelerators for Future Colliders \nAbstract: Particle physics motivates next generations of colliders ranging from a fraction of a TeV for precision Higgs physics to the 10 TeV parton Center of Mass (pCM) scale for both broad new physics and deep characterization of the Higgs sector. Designs for Higgs factory colliders are being formalized with the aim of a project late in the decade. The 10 TeV pCm range will place radical new demands on accelerator capability\, efficiency\, and cost. At the same time\, accelerator science is advancing rapidly with a set of new technologies under development that make it feasible to address this frontier. These technologies\, including high field magnets for proton machines\, muon colliders incorporating cooling\, and high gradient linear wakefield lepton colliders all require development in order to allow us to make a confident\, informed decision on the path forward. These colliders\, a combination of general and targeted R&D\, and interactions with the detector and particle physics community to develop them will be discussed. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Roy Aleksan (CEA-Saclay) - Title: Status of the Future Circular Collider (FCC)
DESCRIPTION:Research Progress Meeting \nDate: March 5\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Roy Aleksan (CEA-Saclay) \nTitle: Status of the Future Circular Collider (FCC) \nAbstract: \nWhile the LHC is continuing its outstanding program\, one needs to decide what the next large accelerator project in particle physics will be. There is a general global consensus that an e+e- collider is the next priority. In accordance with the 2020 European Strategy Update\, the technical and financial feasibility of a circular high energy hadron collider at CERN with a centre-of-mass energy of at least 100 TeV and with an electron-positron Higgs and electroweak factory as a possible first stage has been launched in Europe. In the present talk\, we shall discuss the status of this endeavor including the physics motivation\, the corresponding technical implications for the detectors as well as the status of the study of the accelerator complex with special emphasis on the e+e- collider. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Brendan Crill (Jet Propulsion Laboratory) - Title: Sensitivity limits to cosmological constraints on early Universe physics: lessons from Planck for future measurements
DESCRIPTION:Research Progress Meeting \nDate: February 27\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Brendan Crill (Jet Propulsion Laboratory) \nTitle: Sensitivity limits to cosmological constraints on early Universe physics: lessons from Planck for future measurements \nAbstract: \nThe past several decades have seen enormous breakthroughs in the understanding of fundamental physics of the Universe through observations of the cosmic microwave background (CMB) and large scale structure.  A synergy of rapid advances in technology\, data analysis capabilities\, and theory has led to an abundance of measurements\, which in turn has seen the success of the Lambda-CDM model seeded by early-Universe inflation.  This theory explains observations very few free parameters has emerged at explaining the observed structure of the universe. \nFurther refinements to this model and further characterization of observables in the CMB are a high priority for a deeper understanding of the nature of the physics of inflation and the evolution of structure across cosmic time.  This will come about through measurements of non-Gaussianity\, lensing\, and the imprint of tensor modes in large-scale CMB polarization among other observables. \nTo achieve these refinements\, projects have focused on improvements in raw sensitivity via new and more powerful detectors arrays with vastly more elements. \nHowever\, the success of earlier measurements has only come about through understanding and correction of systematic errors\, understanding astrophysical foregrounds: more powerful instruments with better sensitivity are likely to uncover new challenges. \nHere I describe lessons learned from the Planck mission at handling unforeseen instrumental and observational challenges and discuss prospects for fulfilling the sensitivity promise offered by large-scale structure projects such as SPHEREx and future CMB measurements. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Clara Verges (Harvard) - Title: A new era for cosmology with current and next-generation CMB experiments
DESCRIPTION:Research Progress Meeting \nDate: February 20\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Clara Verges (Harvard) \nTitle: A new era for cosmology with current and next-generation CMB experiments \nAbstract: \nCosmology has experienced a considerable surge in the past thirty years\, and is now well established as a precision science. While the standard cosmological model provides an effective description of the observed Universe\, many fundamental questions remain unresolved. From shedding light on the very first fractions of seconds after the Big Bang to looking for exotic physics\, the Cosmic Microwave Background continues to be a unique probe for fundamental physics. The next generation of CMB polarisation observatories\, embodied by CMB-Stage 4 for ground observations\, will explore this window into the Universe in an unprecedented way\, enabling breakthrough science. I will review how current experiments such as the BICEP/Keck telescopes pave the way for this next stage\, by developing efficient technologies and observing strategies\, and by sharpening constraints on theoretical models. I will then discuss the scientific and technological challenges that the CMB community must meet to ensure the success of future experiments. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

In this talk\, I will show that CMB secondary anisotropies contain a wealth of cosmological information and are becoming leading cosmological probes. I will present recent measurements from the Atacama Cosmology Telescope collaboration that have mapped out several of these effects. I will then highlight some challenges for these measurements with upcoming CMB experiments\, and some unique opportunities\, such as tests of the fundamental properties of our Universe. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Lindley Winslow (MIT) - Title: The Search for GUT-Scale Axions: Really Big Magnets and Quantum Sensing
DESCRIPTION:Research Progress Meeting \nDate: February 6\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Lindley Winslow (MIT) \nTitle: The Search for GUT-Scale Axions: Really Big Magnets and Quantum Sensing\n \nAbstract: \nThe particle nature of dark matter remains one of the great open questions in physics. There is a broad category of candidates whose mass is so light that they behave more as waves than as particles. The most well-known is the axion\, which has had a renaissance as a dark matter candidate as theoretical studies have improved our understanding of axion cosmology and advances in quantum sensing and cryogenics have opened new opportunities for detection. In this talk\, I will focus on the search for GUT-Scale axions\, the DMRadio Program and the results from the ABRACADABRA demonstrators. If time permits\, I will also discuss our other R&D efforts that span from searching for primordial black holes to coupling quantum dots to SNSPDs. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Mariel Pettee (LBNL) - Title: Towards a Foundation Model for Fundamental Physics
DESCRIPTION:Research Progress Meeting \nDate: February 1\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Mariel Pettee (LBNL) \nTitle: Towards a Foundation Model for Fundamental Physics \nAbstract: The launch of ChatGPT in November 2022 ignited an ongoing worldwide conversation about the possible impacts of Large Language Models (LLMs) on the way we work. There is little doubt that LLMs will significantly influence many people’s jobs: one prominent study estimated that about 20% of the US workforce could soon see about 50% of their daily tasks influenced by these models. As scientists\, however\, the changes in our workflows since the advent of this technology have been relatively minor. \nWill this still be the case in 10 years? Could an analogous paradigm shift arise from a foundation model trained on a large amount of scientific data\, transforming the way we conduct our research? If so\, what can we learn from the development of other foundation models\, including LLMs\, in their evolution from specialists to (quasi-)generalists? In this talk\, I will present some recent work representing very early potential steps towards a foundation model of fundamental physics as well as perspectives on how we should strive to shape such a model to reflect our highest priorities as scientists.\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Philip Harris (MIT) - Title: You can observe a lot by just watching (new AI strategies for the LHC and beyond)
DESCRIPTION:Research Progress Meeting \nDate: January 25\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Philip Harris (MIT) \nTitle: You can observe a lot by just watching (new AI strategies for the LHC and beyond) \nAbstract: With large amounts of data\, a Higgs boson discovery\, and world-leading constraints on an enormous amount of parameters and interactions\, the Large Hadron Collider has been a phenomenal tool. However\, it has reached the middle of life and is going through a mid-life crisis. We venture in a new direction to show how AI approaches are allowing us to do new\, unprecedented physics measurements\, leading to a mysterious deviation in Higgs boson production at high momentum. Moreover\, we show a new result built on contrastive learning and semi-supervised learning strategies where\, through physics-motivated choices\, we teach an AI to visualize many physics processes simultaneously\, allowing it to solve a variety of downstream tasks in one algorithm. The implications are far-reaching\, including a world-leading Higgs boson identification and new sensitive approaches in AI-based anomaly detection. Finally\, we show a dedicated path for the broad adoption of AI into all aspects of data processing at the Large Hadron Collider and other experiments\, including LIGO\, that are leading to faster\, better\, unprecedented results; the kind of results we believe can revitalize an aging accelerator. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Joseph Bramante (Queen's University) - Title: Back to the Future With High Mass Dark Matter
DESCRIPTION:Research Progress Meeting \nDate: January 18\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Joseph Bramante (Queen’s University) \nTitle: Back to the Future With High Mass Dark Matter \nAbstract: A number of theories predict that dark matter is a supermassive particle or composite state. Discovering dark matter in this high mass regime requires different approaches. I will survey recent developments\, including composite dark matter that produces unique signatures in underground experiments\, dark matter detectable through its fusion of nuclei in Antarctic ice\, and halo substructures heating neutron stars. I will also survey certain experiments from the 80s and 90s\, which still provide the best sensitivity to many varieties of high mass dark matter. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Emily Perry (UCL) - Title: Towards the discovery of galactic dark matter: the LZ experiment and beyond
DESCRIPTION:Research Progress Meeting \nDate: December 19\, 2023 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Emily Perry (UCL) \nTitle: Towards the discovery of galactic dark matter: the LZ experiment and beyond\n \nAbstract: \nThe discovery of the nature of dark matter is internationally recognised as one of the highest priorities in science. Its discovery would bring forward a new era in physics and astronomy\, simultaneously solving the near 100 year old missing mass problem and delivering the first evidence of physics Beyond the Standard Model (BSM). Dual phase xenon (Xe) time projection chambers (TPCs) have been dominating the search for dark matter for the past 10 years. Now not only targeting WIMPs of mass > 3 GeV/c2\, but due to their scalability and advanced technologies\, boast world leading sensitivity to other BSM-physics and rare or exotic neutrino physics. \nThe LUX ZEPLIN (LZ) dark experiment operates at the Sanford Underground Research Facility in South Dakota and is the most sensitive and largest of all Xe TPCs ever constructed. In its first science run of only 60-livedays the experiment has set the world-leading constraints on the existence of WIMPs down to a mass of 9 GeV/c2. This seminar will highlight some of the key work that has led to this result with focus on some of my specific contributions. Giving an exciting glimpse of what the future holds for LZ\, I will present the innovative work that is being done on the ramp up to the next science results. I will also discuss both the short and long term future of LZ and the path to an historic dark matter discovery. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Deion Fellers (University of Oregon) - Title: FASER’s Search for Dark Photons and Neutrinos
DESCRIPTION:Research Progress Meeting \nDate: December 14\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Deion Fellers (University of Oregon) \nTitle: FASER’s Search for Dark Photons and Neutrinos\n \nAbstract: FASER is an experiment at the LHC that is designed to search for light\, weakly-interacting particles produced in the far-forward direction from proton-proton collisions at the ATLAS interaction point (IP1). The detector is positioned 480 m downstream of IP1 and aligned with the beam collision axis\, where particles must traverse LHC magnets and approximately 100 m of rock and concrete before reaching FASER. The novel location of the experiment provides both a low background environment and a high-intensity flux of long-lived particles. This talk will provide an overview of the FASER detector and present our first physics results\, where we used a dataset collected at center-of-mass energy √s =13.6 TeV in 2022\, during LHC Run 3\, to directly observe neutrino interactions at a particle collider experiment for the first time and also to probe previously unconstrained phase space of the dark photon with couplings ϵ∼10−5−10−4 and masses ∼10 MeV – 100 MeV. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Christina Wang (Cal Tech) - Title: Search for New Physics with CMS and Quantum Sensors
DESCRIPTION:Research Progress Meeting \nDate: December 12\, 2023 \nTime: 1:00- 2:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Christina Wang (Cal Tech) \nTitle: Search for New Physics with CMS and Quantum Sensors\n \nAbstract: \nI will present two new highly complementary approaches to search for physics beyond the Standard Model. The searches are enabled by a first-of-its kind reconstruction technique to search for long-lived particles (LLPs) using the Compact Muon Solenoid (CMS) and by new advances in quantum sensing technology to search for axions. \nI will first discuss a search for physics beyond the Standard Model by searching for LLPs using a novel technique to reconstruct decays of LLPs in the CMS muon detectors. The innovative LLP reconstruction technique has been shown to be sensitive to a broad range of LLP decay modes and to LLP masses below GeV. The search yields competitive sensitivity for proper lifetime from 0.1m to 1000m with the full Run2 dataset recorded at the LHC. \nIn the second part of the talk\, I will discuss searching for axions with a low noise quantum sensor\, SNSPDs (superconducting nanowire single photon detectors). The BREAD (Broadband Reflector Experiment for Axion Detection) experiment searches for axions or dark photons using a parabolic mirror to focus axion-converted photons to the SNSPDs. The SNSPDs allow us to be sensitive to 0.04 – 1 eV axions and dark photons\, due to their sensitivity to 0.04 – 1 eV photons. In this talk\, I will present the progress towards a first stage dark photon pilot experiment with a focus on SNSPD characterization. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Gerrit Farren (Cambridge) - Title: The Atacama Cosmology Telescope: Probing the large scale structure with ACT DR6 CMB lensing and cross-correlation with unWISE
DESCRIPTION:Research Progress Meeting \nDate: December 7\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Gerrit Farren (Cambridge) \nTitle: The Atacama Cosmology Telescope: Probing the large scale structure with ACT DR6 CMB lensing and cross-correlation with unWISE\n \nAbstract: I will present work on probing the large scale structure of the universe using CMB lensing from the upcoming Data Release 6 of the Atacama Cosmology Telescope (ACT) and cross-correlations with galaxies from the unWISE galaxy catalog. My talk will focus on how our highly competitive constraints from CMB lensing cross-correlations can provide insight into the widely discussed “S8/sigma8 tension”. For this purpose I will briefly introduce the high fidelity CMB lensing reconstruction obtained by the ACT Collaboration and results from the analysis of the lensing auto-correlation. I will discuss results from the cross-correlation between ACT CMB lensing and unWISE galaxies\, highlighting improvements to the analysis pipeline compared to previous work on the cross-correlation between Planck CMB lensing and unWISE by some of my collaborators (Krolewski et al. 2021). I will also touch on our recent work to extend such cross-correlation analyses beyond two-point correlations using the first detection of the galaxy-galaxy-CMB lensing bispectrum. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Michael Williams (University of Michigan) - Title: Searches for Particle Dark Matter with LZ and TESSERACT
DESCRIPTION:Research Progress Meeting \nDate: December 5\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Michael Williams (University of Michigan) \nTitle: Searches for Particle Dark Matter with LZ and TESSERACT\n \nAbstract: The search for particle dark matter is one of the primary challenges in modern physics. Direct detection experiments typically rely on measuring signals produced when dark matter particles recoil off a detector target. In this talk\, I will first discuss the LUX-ZEPLIN (LZ) experiment\, which uses a dual-phase xenon time projection chamber to look for WIMP dark matter that recoils off the xenon nucleus. I will discuss LZ detector construction\, first WIMP search results\, and limits on effective field theory (EFT) searches of dark matter. I will then discuss the search for low-mass dark matter with TESSERACT; this encompasses interactions with two types of novel\, ultra-sensitive detectors – SPICE and HeRALD. Both SPICE and HeRALD use transition edge sensors (TESs) for cryogenic readout\, while using different targets: polar crystals and superfluid helium-4\, respectively. I will describe the development and first measurements of new Iridium-Platinum (IrPt) TESs and the commissioning of the new HeRALD detector at LBNL. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Michael MacKenzie (Northwestern University) - Title: Searches for Charged Lepton Flavor Violation at CMS and Mu2e
DESCRIPTION:Research Progress Meeting \nDate: November 30\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Michael MacKenzie (Northwestern University) \nTitle: Searches for Charged Lepton Flavor Violation at CMS and Mu2e\n \nAbstract: Neutrino oscillations have shown that lepton flavor is not a conserved quantity. Charged lepton flavor violation (CLFV) is suppressed by the small neutrino masses well below what is experimentally observable\, though new physics models predict higher rates of CLFV. I will discuss a current search at the CMS experiment for the CLFV decay of the Z boson\, focusing on the search for Z→e µ. I will also discuss the upcoming search for CLFV µ− → e− conversion at the Mu2e experiment at FNAL. The Mu2e experiment aims to improve the sensitivity to µ− → e− conversion by a factor of 10\,000. I will present the expected µ− → e− conversion sensitivity during Run 1 at Mu2e. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Lee Hagaman (University of Chicago) – Title: Investigating Short-Baseline Neutrino Anomalies Using MicroBooNE
DESCRIPTION:Research Progress Meeting \nDate: November 28\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Lee Hagaman (University of Chicago) \nTitle: Investigating Short-Baseline Neutrino Anomalies Using MicroBooNE\n \nAbstract: The MicroBooNE experiment is a liquid argon time projection chamber (LArTPC) in the Booster Neutrino Beam at Fermilab. One of its primary goals is to address the 4.8 sigma MiniBooNE Low Energy Excess (LEE). Leveraging the unique capabilities of LArTPC technology to identify hadronic activity and separate photon and electron showers\, MicroBooNE has achieved a search for an electron neutrino excess (potentially due to a sterile neutrino)\, as well as a search for a single photon excess from neutral current Delta radiative decays. In this talk\, we will present a comprehensive overview of these results\, as well as recent advancements toward new searches for single photons and electron-positron pairs as explanations of the MiniBooNE LEE. These include a more sensitive search for Delta radiative decays\, a search for coherent-like single photon production\, an inclusive single photon search\, and searches for electron-positron pairs from dark sector models. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Roohi Dalal (Princeton) - Title: New Cosmology Constraints from the Hyper Suprime-Cam Year 3 Data Release
DESCRIPTION:Research Progress Meeting \nDate: November 21\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Roohi Dalal (Princeton) \nTitle: New Cosmology Constraints from the Hyper Suprime-Cam Year 3 Data Release\n \nAbstract: The Hyper Suprime-Cam (HSC) survey is the deepest present-day weak lensing experiment\, going to ~26 mag with exquisite image quality. This combination of depth and image quality achieved by HSC allows us to probe cosmology using weak gravitational lensing up to high redshifts\, and these analyses serve as important preparatory studies for the next generation of weak lensing surveys\, particularly the Vera C. Rubin Observatory. I will discuss our constraints on cosmological parameters using weak lensing cosmic shear power spectra measured from the Year 3 shear catalog of HSC\, covering 416 square degrees of the northern sky. I will describe our cosmological analysis\, including the steps we take to prevent confirmation bias as well as our modeling of various systematic effects. The quantity best constrained by our analysis is the parameter S8\, which describes the clumpiness of the matter distribution in the universe. From our analysis\, and other weak lensing analyses with different surveys\, there is a 2-3 sigma detection of a tension in the S8 measurements from weak lensing and those from the cosmic microwave background. While this could suggest that our cosmological model is incomplete\, I will discuss ongoing and future work that can further shed light on this tension\, including an improved modeling of baryonic feedback at small scales. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Aleksandra Kusiak (Columbia) - Title: Probing the Ionized Gas Thermodynamics in Distant Galaxies with the Sunyaev-Zel’dovich Effect
DESCRIPTION:Research Progress Meeting \nDate: November 14\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Aleksandra Kusiak (Columbia) \nTitle: Probing the Ionized Gas Thermodynamics in Distant Galaxies with the Sunyaev-Zel’dovich Effect\n \nAbstract: The Sunyaev-Zel’dovich Effect—the Doppler boost of low-energy Cosmic Microwave Background photons scattering off free electrons in galaxies and clusters in the late Universe—is an excellent probe of ionized gas residing in distant galaxies. Its two main constituents are the kinematic SZ effect (kSZ)\, where electrons have a non-zero line-of-sight (LOS) velocity and which probes the electron momentum\, and the thermal SZ effect (tSZ)\, where electrons have high energies due to their temperature\, and which probes the electron integrated pressure. These two effects provide complementary information necessary to constrain the thermodynamic profile of gas residing in distant galaxies\, which can be further used to understand feedback processes\, a necessary ingredient to describe the evolution of the large-scale structure in our Universe and galaxy formation. Both tSZ and kSZ can be measured in cross-correlation with large-scale structure\, e.g.\, galaxies. \nIn this talk\, I will discuss my past and ongoing measurements of the SZ-galaxy cross-correlations with unWISE galaxies\, including the projected-fields kSZ. unWISE is a galaxy catalog containing over 500 million galaxies on the full sky and consists of three subsamples of mean redshifts z=0.5\, 1.1\, 1.5\, whose halo occupation distribution I have already constrained. If time permits\, I will also present my ongoing work on mitigating foregrounds in the SZ cross-correlations\, particularly the Cosmic Infrared Background (CIB). \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Kelly Stifter (Fermilab) - Title: Leveraging quantum sensors to shine new light on searches for low-mass dark matter

Three decades of experiments have been searching for dark matter interactions over a wide range of candidate dark matter masses and all have come up empty-handed. Nevertheless\, there remain large swaths of unexplored\, well-motivated particle dark matter models that are currently inaccessible through existing detector technologies. One path to probe these remaining particle dark matter models is through the use of low-threshold quantum sensors. In this talk\, I will review the landscape of dark matter direct detection\, outline the potential role of quantum sensors in particle detection\, and detail the early results from a calibration system critical to realizing these individual devices as fully-fledged experiments. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

In recent years\, a new paradigm has emerged: very large models trained on highly diverse training data have demonstrated remarkable capabilities across hundreds of tasks. Many billions of dollars have since been invested in training and deploying such models. In this talk\, I will review some of these developments with a focus on the phenomenon of generalization: as models scale\, what changes? What do we know about the internal functioning of these models and how that emerges during training? What does this portend for the future? I will finally speculate\, with audience participation\, on three potential relationships with physics: the ‘physics’ of model training\, the use of models as scientific assistants\, and the direct use of models to study physical phenomena. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

For decades\, such a signal has been predicted from binaries of supermassive black holes (SMBHs). I will present NANOGrav’s recent data and our interpretation of the signal as produced by SMBH binaries. I will show that these GWs encode a wealth of new information about SMBH formation and evolution. Now\, the race is on for the next expected measurements: detection of anisotropy in the GW background\, and individual loud binaries. These measurements would confirm the origin of the GWs\, provide a crucial testbed for the future LISA mission\, and open a new multi-messenger window into the Universe. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

While the first two are theoretically under good control and systematically improvable using perturbative techniques\, hadronization relies on the use of phenomenological models. I will review the first attempts to use Machine Learning architectures to describe hadronization\, with the ultimate goal to train directly on data. The first practical side product of this effort is an algorithm for faster evaluation of uncertainties associated with the Lund string model implemented in Pythia. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Jia Liu (Kavli IPMU University of Tokyo) - Title: Neutrinos\, baryons\, cosmic web\, and COVID19
DESCRIPTION:Research Progress Meeting \nDate: September 26\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jia Liu (Kavli IPMU University of Tokyo) \nTitle: Neutrinos\, baryons\, cosmic web\, and COVID19\n \nAbstract: This won’t be your usual seminar\, but rather a report back since I left Berkeley two years ago. Despite barely having made it to campus or the lab due to mat leave + COVID\, I managed to work with many Berkeley people on various projects\, almost all of which happened serendipitously. I will touch upon the topics mentioned in the title. I will also discuss prospects for Stage IV cosmology\, in terms of joint simulations and analysis with CMB and LSS surveys. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Naoko Kurahashi Neilson (Drexel) - Title: Neutrino Astronomy\, From Dream to Reality
DESCRIPTION:Research Progress Meeting \nDate: September 21\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Naoko Kurahashi Neilson (Drexel) \nTitle: Neutrino Astronomy\, From Dream to Reality\n \nAbstract: The Universe has been studied using light since the dawn of astronomy\, when starlight captured the human eye. The IceCube Neutrino Observatory\, located at the geographic South Pole\, observes the Universe in a different and unique way: in high-energy neutrinos. IceCube’s discovery in 2013 of a diffuse celestial neutrino radiation started an era of neutrino astronomy. Searches for astronomical sources responsible for creating these neutrinos have covered broad source types while combating background event rates that are 6 orders of magnitude higher. This year\, the first observation of our own Milky Way galaxy in neutrinos was announced in June. This talk will cover how this observation was made\, other milestone observations by IceCube\, and the state of neutrino astronomy. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Uros Seljak (LBNL) - Title: AI for Physics\, Physics for AI
DESCRIPTION:Research Progress Meeting \nDate: September 14\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Uros Seljak (LBNL) \nTitle: AI for Physics\, Physics for AI\n \nAbstract: Artificial Intelligence (Machine Learning) is revolutionizing many aspects of our life\, but its success stories in physics and astronomy are rare and limited to a few subfields only. I will argue that this is because physics applications require development of physics specific AI methods\, rather than using off the shelf methods from the AI community. A few examples of physics specific nature of the data are large dimensionality of the data\, stochastic nature of the data\, and symmetries. I will argue that learning the data structures first using generative learning approaches such as Normalizing Flows enables not only better learning\, but also provides additional information on robustness\, such as anomaly detection. These methods applied to cosmology data show the promise of up to an order of magnitude improvement relative to traditional methods. Physics ideas have also influenced the development of AI\, and many of these have been based on stochastic processes and sampling. I will discuss recently developed MicroCanonical Hamiltonian and Langevin Monte Carlo\, which are a new class of sampling methods that outperform previous state of the art such as Hamiltonian Monte Carlo\, in some cases by orders of magnitude. These new sampling methods will in turn enable solutions of physics problems that were not possible before\, in a wide range of fields from cosmology to lattice QCD. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Paul Stankus (Brookhaven National Laboratory) - Title: Quantum-Enhanced Astronomy For Both Fun and Profit
DESCRIPTION:Research Progress Meeting \nDate: September 7\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Paul Stankus (Brookhaven National Laboratory) \nTitle: Quantum-Enhanced Astronomy for Both Fun and Profit\n \nAbstract: Quantum devices are finding their way to improving many kinds of technologies\, at an increasing pace. We will review ideas for how astronomical measurements\, particularly using interferometers\, can be improved — in some cases greatly so — through the new application of quantum devices such as quantum memories\, single-photon sources\, quantum repeaters\, quantum teleportation\, and more. Then we will take a look at active experimental work in this area and prospects for near-future instruments. Lastly\, we will discuss interesting astrophysical observations that could be enabled by quantum enhancement\, including distance ladder measurements\, exoplanet spectra\, and even low-frequency gravitational waves\, among others. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
