SUMMARY:Speaker: Ben Allanach (Cambridge) - Title: Z' bosons in light of B-anomalies
DESCRIPTION:Research Progress Meeting \nDate: August 28\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Ben Allanach (Cambridge) \nTitle: Z’ bosons in light of B-anomalies \nAbstract: Many measurements of b->s transitions (when accompanied by a di-muon pair) disagree with state-of-the-art Standard Model (SM) predictions. On the other hand\, many other measurements\, including those measuring lepton flavour universality\, are in rough agreement with the SM.\nWe shall review such measurements and give a broad overview of the SM predictions. Z’ bosons with family-dependent couplings can significantly improve global fits. We give an example of a successful model\, re-cast LHC searches for it and provide HL-LHC sensitivity estimates. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Heather Gray (LBNL) and Simone Pagan Griso (LBNL) - Title: What's next for CERN? Summary of the 2025 European Strategy for Particle Physics Open Symposium
DESCRIPTION:Research Progress Meeting \nDate: September 4\, 2025 \nTime: 3:30pm-4:30pm [Note special time]  \nLocation: 50-4-Auditorium [Note special location] \nSpeaker: Heather Gray (LBNL) and Simone Pagan Griso (LBNL) \nTitle: What’s next for CERN? Summary of the 2025 European Strategy for Particle Physics Open Symposium \nAbstract: CERN is undergoing a planning exercise to determine its long-term strategy in particle physics; this exercise has some similarity to the Snowmass/P5 process\, but with some differences.\nCenter to this strategy is what large-scale projects CERN will be undertaking after the LHC and its upgraded High-Luminosity LHC operations stop at around 2041.\nThis symposium represented the only general open meeting to showcase the current ideas and the received community inputs that were due in March 2025. It represented a middle-point before the appointed group starts drafting a report that is expected to be preliminarily available around the end of the year.\nIn this seminar\, we will summarize what has been shown and give our main take-aways from this symposium and the strategy process. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Alan Poon (LBNL) - Title: Recent Results and Status of the Neutrinoless Double-Beta Decay Experiment LEGEND
DESCRIPTION:Research Progress Meeting \nDate: September 11\, 2025 \nTime: 4:00pm-5:00pm   \nLocation: 70A-3-3377 [Note special location] \nSpeaker: Alan Poon (LBNL) \nTitle: Recent Results and Status of the Neutrinoless Double-Beta Decay Experiment LEGEND \nAbstract: The Large Enriched Germanium Experiment for Neutrinoless ββ Decay (LEGEND) is a phased international program designed to answer one of the highest-priority questions in fundamental physics — whether neutrinos are their own anti-particles. Its first phase\, LEGEND-200\, reuses the cryostat of a previous-generation experiment\, GERDA\, in Hall A of the Laboratori Nazionali del Gran Sasso (LNGS) underground laboratory in Italy to house up to 200 kg of 76Ge-enriched high-purity germanium (HPGe) detectors. In this talk\, I will present the latest results from LEGEND-200’s search for the lepton-number-violating neutrinoless double-beta decay. I will also provide a synopsis of the planning of the second phase of the experiment\, LEGEND-1000. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Daniel Baxter (Fermilab) - Title: A QUIET place: Fermilab’s Underground Facilities for Quantum Sensing
DESCRIPTION:Research Progress Meeting \nThis is a joint seminar with the Interdisciplinary Instrumentation Colloquium (IIC).  \nDate: September 16\, 2025 \nTime: 4:00- 5:00 pm \nLocation: 50-4-Auditorium  [Note location] [In-Person and HYBRID]  \nSpeaker: Daniel Baxter (Fermilab) \nTitle: A QUIET place: Fermilab’s Underground Facilities for Quantum Sensing\n \nAbstract: The infrastructure associated with building a large accelerator complex created some very unique spaces at Fermilab. In particular\, the MINOS tunnel\, excavated as part of the NuMI neutrino beam delivering neutrinos to the MINOS\, MINERVA\, and NOVA experiments\, is an easily-accessible 100m underground experimental space. The rock overburden at this depth blocks 99.5% of all cosmic ray muons\, and nearly all hadronic showers\, creating a unique\, low-background environment for novel detector development and calibration. \nThe NEXUS and QUIET laboratories\, each equipped with dilution refrigerators for 10mK detector operation\, are harnessing this opportunity. I will highlight the unique capabilities of these testbeds\, as well as some of the interesting results that have come out of them. I will briefly touch on some of our ongoing studies and proposed experiments for the near future. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/97314813383?pwd=LhetsZ74BUU2cbFP7ZZCye8ofksaUp.1 \nMeeting ID: 973 1481 3383 \nPasscode: 631580

SUMMARY:Speaker: Jim Strait (LBNL) - Title: CMB-S4: birth\, life and death of a major science project
DESCRIPTION:Research Progress Meeting \nDate: September 25\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jim Strait (LBNL) \nSlides: Download slides \nTitle: CMB-S4: birth\, life and death of a major science project \nAbstract: CMB-S4 was envisioned to be a comprehensive ground-based CMB experiment to make transformative discoveries and new insights in fundamental physics\, cosmology\, astrophysics\, and astronomy. It was conceived as a way to unite the entire CMB community to enable a ground-based experiment with capabilities beyond that of any of the smaller individual experiment to realize the enormous potential of CMB measurements for understanding the origin and evolution of the Universe\, from the highest energies at the dawn of time through the growth of structure to the present day. CMB-S4 was launched with great promise and enthusiasm at the 2013 Snowmass Summer Study\, grew into a large collaboration\, built a capable project organization\, developed an advanced technical design and scientific strategies\, was endorsed by multiple high-level advisory committees\, but ultimately was cancelled by the funding agencies in 2025. In this talk I will summarize the history and accomplishments of CMB-S4\, and provide an analysis of why it did not succeed. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Xinran Li (LBNL) - Title: Athermal phonon detectors for light dark matter search\, go small and go large
DESCRIPTION:Research Progress Meeting \nDate: October 2\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Xinran Li (LBNL) \nTitle: Athermal phonon detectors for light dark matter search\, go small and go large \nAbstract: Light dark matter below 100MeV could only deposit sub-eV energies in detectors\, which is invisible to traditional solid state ionizing detectors. Athermal phonon detectors that use superconducting sensors to read out the phonon signals from the target crystals have the potential to achieve sub-eV energy threshold.\nAs a member of the TESSERACT collaboration\, I work on the development of transition edge sensors (TESs). Our recent DM search achieved 1.5eV threshold and extended the constraint on DM mass down to 44MeV with a 0.23g silicon detector. Our latest understanding of the stress-induced low energy excess events suggests that an even smaller target could help us achieve sub-eV threshold.\nOn the other hand\, to go large\, envisioning the next generation 10~100g scale large light dark matter detector\, kinetic inductance devices (KIDs) have the advantages of being easily scalable through multiplexing. I lead the effort to develop Hafnium (Hf) low critical temperature (Tc) KIDs for phonon sensing. The internal energy resolution of Hf KID is compatible to TESs\, while improving phonon collection efficiency is challenging. Several paths forward are defined and being actively pursued\, including quasiparticle trapping\, phonon blocking\, and parametric amplification. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Tim Nelson (SLAC) - Title: Light Dark Matter eXperiment: A Discovery Experiment for Sub-GeV Dark Matter at SLAC
DESCRIPTION:Research Progress Meeting \nDate: October 14\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Tim Nelson (SLAC) \nTitle: Light Dark Matter eXperiment: A Discovery Experiment for Sub-GeV Dark Matter at SLAC \nAbstract: As searches for WIMPs approach fundamental sensitivity limits\, interest in the more general class of thermal relics has emerged\, where these dark matter candidates give rise to clear and testable predictions in small\, accelerator-based experiments. The Light Dark Matter eXperiment (LDMX) — proposed to operate in End Station A at SLAC using LCLS-II drive beam — is uniquely capable of searching for sub-GeV thermal relics that can explain the observed dark matter abundance. In this talk\, I will review the motivations for these searches\, describe how LDMX works\, and discuss the status of efforts to realize the experiment. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Chuan-Hong Liu (LBNL) - Title: Nonequilibrium Quasiparticles in Superconducting Quantum Bits
DESCRIPTION:Research Progress Meeting \nDate: October 16\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Chuan-Hong Liu (LBNL) \nTitle: Nonequilibrium Quasiparticles in Superconducting Quantum Bits \nAbstract: The ideal superconductor offers a pristine host for the fragile quantum states of a superconducting quantum computer. With an energy gap protecting against low-energy excitations\, qubits should\, in principle\, be isolated from unwanted modes that cause irreversible decay of quantum information. In practice\, however\, a significant density of excitations persists above the superconducting ground state\, even at ultralow temperatures. These excitations\, known as quasiparticles\, can drain energy from the qubit mode and induce dephasing\, thereby degrading quantum computer’s performance. In this talk\, we will discuss two dominant mechanisms of quasiparticle generation: resonant millimeter-wave absorption and impacts from high-energy particles. We further show that careful device design\, combined with a well-shielded operating environment\, provides effective strategies to mitigate quasiparticle poisoning. A deeper understanding of these processes will be essential for realizing the next generation of superconducting quantum computers that are resilient against quasiparticle-induced errors. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Daniel Carney (LBNL) - Title: Experimental quantum gravity
DESCRIPTION:Research Progress Meeting \nDate: October 23\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Daniel Carney (LBNL) \nTitle: Experimental quantum gravity \nAbstract: This will be an informal talk on some ideas related to testing aspects of quantum gravity in experiments. There are two basic directions I will cover. One is experiments aimed at determining whether the gravitational field is a quantized degree of freedom in the real world. In particular\, I will discuss an experiment in this direction that we developed joint with Holger Muller on campus and which is about to come online. The other direction is a bit newer and something that I think our quantum groups at LBL could contribute to: quantum simulation of holographic physics (e.g.\, AdS/CFT). \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Gianpaolo Carosi (LLNL) - Title: Tuning into Dark Matter with the ADMX experiment
DESCRIPTION:Research Progress Meeting \nDate: November 6\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Gianpaolo Carosi (LLNL) \nTitle: Tuning into Dark Matter with the ADMX experiment \nAbstract: The primordial axion remains one of the best solutions to both dark matter and the strong-CP problem (or why the neutron doesn’t have a measurable electric-dipole moment). The Axion Dark Matter Experiment (ADMX)\, which started at Lawrence Livermore National Laboratory in the mid-1990s\, is the DOE Flagship search for these particles in the micro-eV mass range. The experiment uses tunable resonant cavities in a large static magnetic field to enhance the conversion of dark matter axions to detectable microwaves in the GHz range. Quantum-limited amplifiers based on superconducting Josephson Junction circuits are critical to allow the search to be sensitive enough to rapidly scan the frequencies where the axion may exist. Here I will describe the detection strategy of ADMX\, the progress made so far and outline the potential next phase of the experiment dubbed ADMX-Extended Frequency Range (ADMX-EFR). I will also discuss LLNL’s involvement in the nascent BREAD broadband axion search. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Xiaochen Ni (University of Washington) - Title: Development of TopmetalSe: CMOS/aSe Hybrid Detectors for Neutrino Physics
DESCRIPTION:Research Progress Meeting \nDate: November 20\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Xiaochen Ni (University of Washington) \nTitle: Development of TopmetalSe: CMOS/aSe Hybrid Detectors for Neutrino Physics \nAbstract: The Selena experiment couples an amorphous selenium (aSe) ionization target to a complementary metal–oxide–semiconductor (CMOS) pixel array as an imaging detector for next-generation neutrino physics. Hybrid a-Se/CMOS detectors provide a unique combination of high-Z stopping power\, direct charge conversion\, and fine-pitch pixel imaging. These properties enable precise reconstruction of ionization tracks with excellent spatial resolution\, allowing for low-background measurements with advanced event classification. In this talk\, I will present Selena’s capabilities for a neutrinoless double-beta decay search and share the ongoing detector R&D\, including the design\, fabrication\, and characterization of its first prototype pixel array\, TopmetalSe\, produced in the SkyWater 130 nm open-source CMOS process. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

DESCRIPTION:Research Progress Meeting \nDate: November 25\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Mun Jung Jung  (University of Chicago) \nTitle: Quasielastic–like Interactions of Muon Neutrinos in SBND \nAbstract: The Short-Baseline Near Detector (SBND)\, the near detector of the Short-Baseline Neutrino (SBN) program at Fermilab\, has completed a successful Run 1\, delivering an unprecedented dataset of neutrino-argon interactions. One of the first targets for SBND is the muon neutrino charged-current quasielastic–like channel\, the dominant exclusive topology in SBN and a sensitive probe of nuclear effects. In this talk\, I’ll present progress toward the first SBND physics results and discuss how the quasielastic-like channel can be studied to test interaction models and lay the foundation for the broader neutrino-nucleus interaction and oscillation physics program at SBND and SBN. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Josef Sorenson (University of New Mexico) - Title: Rare B Meson Decays and Precision Timing for Future Colliders
DESCRIPTION:Research Progress Meeting \nDate: December 2\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Josef Sorenson (University of New Mexico) \nTitle: Rare B Meson Decays and Precision Timing for Future Colliders \nAbstract: Flavor Changing Neutral Currents (FCNCs) are suppressed in the Standard Model (SM). Approximately one in ten billion neutral B mesons decays into pairs of oppositely charged muons. This suppression\, combined with the precise theoretical SM predictions\, makes this decay a promising channel to search for New Physics. I will present progress towards the latest measurement of the decay of B mesons to muon pairs using the ATLAS Run 2 dataset. The High-Luminosity Large Hadron Collider (HL-LHC) provides an excellent opportunity for measuring this channel\, with an expected 3000 fb-1 of p-p collision data. I will present R&D towards precision timing sensors and electronics to deal with the adverse radiation and pileup environments in the HL-LHC and future colliders. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

I will present my work developing and deploying SPINE\, an end-to-end machine learning reconstruction algorithm for neutrino events in LArTPCs. SPINE provides high-quality particle identification and interaction clustering\, enabling precision neutrino-argon cross-section measurements and high-quality neutrino selections for oscillation analyses. I will demonstrate SPINE’s impact through a muon neutrino charged current inclusive selection\, comparing traditional reconstruction methods to the SPINE-based approach\, and discuss how this reconstruction capability supports the SBN program’s physics goals for both cross-section measurements and oscillation analyses. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

This talk details the tools in development to make that a reality for tracks associated with a large ionization energy loss (dE/dx). I will place particular emphasis on a new dE/dx measurement from gaseous drift tubes in the ATLAS Muon Spectrometer\, born from a detailed understanding of detector hardware and readout electronics. I will present this measurement alongside other Muon-Spectrometer-based tools that aid us in the hunt for long-lived massive and/or di-charged particles\, including dedicated reconstruction techniques. I will also discuss the progress of the New Small Wheel upgrade of the ATLAS Muon Spectrometer\, and outline the commissioning of the MicroMegas detector trigger in view of the upcoming High-Luminosity LHC era. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

In 2024\, the DUNE collaboration collected its first neutrino beam data using the 2×2 Demonstrator\, a prototype for DUNE’s liquid argon near detector (ND-LAr) located in the Neutrinos at the Main Injector (NuMI) beamline at Fermi National Accelerator Laboratory (Fermilab). This talk will explore how these 2×2 data are critical in validating key ND-LAr design choices\, such as the use of liquid argon time-projection chamber (LArTPC) technology\, optically isolated modules\, and pixelated charge readout. Furthermore\, this talk will explain how these 2×2 data are essential in fulfilling ND-LAr’s purpose of reducing beam\, detector\, and cross section systematic uncertainties in DUNE oscillation measurements.\n \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Livio Calivers (University of Bern) - Title: Light Detection for Modular Liquid Argon Neutrino Detectors: From Concept to Beam Data in the DUNE Near Detector
DESCRIPTION:Research Progress Meeting \nDate: January 8\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Livio Calivers\, University of Bern \nTitle: Light Detection for Modular Liquid Argon Neutrino Detectors: From Concept to Beam Data in the DUNE Near Detector \nAbstract: The Deep Underground Neutrino Experiment (DUNE) aims to perform precision measurements of neutrino oscillations\, which require stringent control of systematic uncertainties at the Near Detector. A major challenge arises from the severe interaction pile-up in liquid-argon time projection chambers operating near the origin of the intense neutrino beam. This talk describes how fast scintillation-light detection is exploited to enhance event reconstruction and interaction timing in the modular Liquid Argon Near Detector (ND-LAr). The design of the ArCLight system is presented—a fully dielectric\, SiPM-based light detector integrated directly into the TPC drift field\, providing efficient photon collection with minimal inactive material. Results from the DUNE 2×2 Demonstrator operated in the NuMI beam at Fermilab include the observation of neutrino interactions and a demonstrated sub-4 ns timing resolution\, sufficient to resolve the accelerator bunch structure and enable in-spill interaction separation. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Matthias Vigl (Technical University of Munich) - Title: Machine-Learning Scaling Laws for LHC Physics: How Scale Unlocks Breakthrough Gains in Physics Sensitivity
DESCRIPTION:Research Progress Meeting \nDate: January 13\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Matthias Vigl (Technical University of Munich) \nTitle: Machine-Learning Scaling Laws for LHC Physics: How Scale Unlocks Breakthrough Gains in Physics Sensitivity \nAbstract: High Energy Physics and deep learning have historically taken different routes to data processing: in collider physics\, performance has been driven by deep\, hand-engineered pipelines that encode decades of domain knowledge\, while modern machine learning has advanced primarily through scale\, leveraging large datasets and increasingly generic model architectures. While machine learning has long been embedded in the HEP analysis pipeline\, the rate of improvement has remained slower than the rapid\, scale-driven progress observed in industry.\nThis talk contrasts physics-driven and scale-driven approaches to data processing and shows how foundation-model principles (scaling laws\, transfer learning\, and end-to-end optimization) can be applied to HEP analyses. Compute-optimal scaling laws are derived for the state-of-the-art ATLAS jet flavor tagger and validated by training models two orders of magnitude beyond previous compute regimes\, yielding predictable performance improvements in line with industry-scale models. When translated into physics sensitivity for flagship ATLAS analyses such as HH(4b) at the High-Luminosity LHC\, these gains correspond to improvements equivalent to multiple years of data taking\, motivating a shift toward large-scale ML model training and deployment within LHC experiments.\n \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

The Muon g-2 Experiment at Fermilab was motivated by a long-standing ~3.5σ discrepancy between theory and experiment and aimed to improve the experimental precision by a factor of four. In 2025\, the collaboration reported its final result based on six years of data\, reaching a precision of 127 parts per billion. This talk will summarize the experimental method\, key systematic challenges\, and the final measurement\, and discuss its implications for ongoing efforts at the precision frontier. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

In this talk I will discuss how we can use line intensity mapping (LIM) of far-IR emission lines to measure large volumes at high redshift. This technique is enabled by advances in millimeter-wave spectrometer technology. I will present two on-chip spectrometer projects: SuperSpec\, which pioneered the concept and was deployed to the Large Millimeter Telescope\, and SPT-SLIM\, a pathfinder LIM experiment at the South Pole. Both projects saw first light in 2025. I will discuss what we’re learning from their first observations and outline the path towards large\, dense focal planes with the sensitivity required for next-generation cosmology. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

DESCRIPTION:Research Progress Meeting \nDate: February 19\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jamie Bock\, JPL \nTitle: Spectrally Mapping the Sky with SPHEREx \nAbstract: Launched in March 2025\, SPHEREx is an all-sky spectral survey satellite designed to address three science goals with a single instrument\, a wide-field imager. SPHEREx probes the physics of inflation through measurements of non-Gaussianity by studying large-scale structure\, surveying a large cosmological volume at low redshifts. The program charts the origin and history of galaxy formation by mapping large-scale spatial power in two deep fields located near the ecliptic poles. SPHEREx also investigates the origin of water and biogenic molecules in the early phases of planetary system formation – from molecular clouds to young stellar systems with protoplanetary disks – by measuring ice absorption spectra. Following in the tradition of all-sky missions\, SPHEREx will be the first all-sky near-infrared spectral survey\, producing four complete all-sky maps that will serve as a rich archive for the astronomy community. With over a billion detected galaxies\, hundreds of millions of high-quality stellar and galactic spectra\, and over a million ice absorption spectra\, the archive will enable diverse scientific investigations across astronomy. Our two-year mission recently completed its first map of the full sky. I will share the performance of the instrument in flight and some early results. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

DESCRIPTION:Research Progress Meeting \nDate: March 5\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Calvin Leung (UC Berkeley) \nTitle: From Radio Interferometry to Astrophysics and Cosmology using Fast Radio Bursts \nAbstract: Since their discovery\, Fast Radio Bursts (FRBs) have ascended into one of the most exciting areas of astrophysics due to their mysterious origin and emerging broad utility as cosmic probes. I will outline how the CHIME/FRB Outriggers array — a widefield VLBI array — leads this growing field. Next\, I will showcase the immense potential of FRBs as probes: of the diffuse baryons in the circumgalactic medium; the feedback processes which drive galaxy evolution; and eventually\, how FRB cross correlations with weak lensing surveys may enable clean measurements of dark matter on megaparsec scales. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: J. Pedro Ochoa-Ricoux (UIC) - Title: First Physics Results from the JUNO Experiment
DESCRIPTION:Research Progress Meeting \nDate: March 19\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: J. Pedro Ochoa-Ricoux (UIC) \nTitle: First Physics Results from the JUNO Experiment \nAbstract: Neutrinos are elusive particles with unique properties that offer key insights into the fundamental structure of matter and the cosmic sources that produce them. The Jiangmen Underground Neutrino Observatory (JUNO) is a next-generation\, 20-kiloton liquid scintillator detector\, the largest of its kind in the world\, located in China and recently brought into operation after more than a decade of design and construction. In this talk\, I will review the initial detector performance and present the first results from the experiment\, based on about 60 days of data\, which provide world-leading estimates of two neutrino oscillation parameters. I will also briefly outline the broader physics program enabled by JUNO and the additional measurements it aims to pursue. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Anže Slosar (BNL) - Title: LuSEE-Night: A lunar radio-astronomy pathfinder.
DESCRIPTION:Research Progress Meeting \nDate: March 26\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Anže Slosar (BNL) \nTitle: LuSEE-Night: A lunar radio-astronomy pathfinder. \nAbstract: LuSEE-Night is a novel collaborative effort between NASA and DOE aiming to land a path-finder radio telescope on the far side of the Moon. The instrument consists of 4 monopole antennas and will observe the radio sky between 0.1Mhz and 50MHz. This observational band is largely inaccessible from the Earth due to ionosphere and radio interference\, but offers potentially transformational information about the early universe. The instrument is manifested for launch on the Firefly Blue Ghost Mission 2\, targeting a landing in spring 2027. The mission will attempt numerous firsts: the first US landing on the lunar far side; the first far-side landing by a private company; the first modern US attempt to survive and operate through a lunar night; the first demonstration of radio calibration from an in-orbit calibrator around any planetary body; and\, crucially\, the first far-side radio instrument to deliver science-grade data. This talk describes the science case\, the instrument design\, and future opportunities for fundamental physics enabled by the lunar far side. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Elliot Lipeles (U Penn) - Title: The Hadron Collider Option
DESCRIPTION:Research Progress Meeting \nDate: April 2\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Elliot Lipeles (U Penn) \nTitle: The Hadron Collider Option \nAbstract: Hadron colliders have enormous physics reach\, but were sidelined in the current cycle of large project planning primarily because of cost. I review the physics motivation and reach of a hadron collider\, along with the technology options\, the interplay of energy and luminosity constraints\, and what they mean for the ultimate project cost as we currently understand it. \n  \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
