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: 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: Colin Hill (Columbia) - Title: Uncovering Physics Beyond the Standard Model in the Cosmic Microwave Background
DESCRIPTION:Research Progress Meeting \nDate: March 12\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Colin Hill (Columbia) \nTitle: Uncovering Physics Beyond the Standard Model in the Cosmic Microwave Background \nAbstract: \nThe cosmic microwave background (CMB) anisotropy remains the cleanest\, most powerful probe of fundamental physics in the cosmos. Measurements of the small-scale CMB temperature and polarization fields are set to undergo transformative improvements in the coming decade\, culminating in the CMB-S4 experiment\, which will open new windows into physics beyond the standard models (BSM) of particle physics and cosmology. I will first discuss my ongoing work in the Atacama Cosmology Telescope collaboration focused on cosmological parameter constraints from high-resolution CMB power spectra\, with a particular emphasis on constraining BSM physics operating just prior to recombination\, including new relativistic particles and new pseudo-scalar fields. I will describe high-precision end-to-end tests of our entire analysis pipeline on realistic\, non-Gaussian sky simulations containing all relevant Galactic and extragalactic foregrounds\, tightly coupled to a detailed instrument model. I will then turn to novel searches for BSM physics in CMB secondary anisotropies\, as could be imprinted by the screening of CMB photons by massive dark photons or axion-like particles. I will show the first results of searches for these signals in CMB data\, enabled by my group’s state-of-the-art needlet internal linear combination code. Finally\, I will discuss new analysis methodologies for more optimally cleaning non-Gaussian foregrounds in CMB maps\, with applications to both primordial B-mode searches and small-scale secondary anisotropy measurements. I will conclude with a look ahead to the prospects for BSM physics from the Simons Observatory and CMB-S4. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Matthias Hohenberger (LLNL) - Title: Demonstrating fusion ignition in the laboratory for the first time
DESCRIPTION:Research Progress Meeting \nDate: March 14\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Matthias Hohenberger (LLNL) \nTitle: Demonstrating fusion ignition in the laboratory for the first time \nAbstract: At approximately 1 am on December 5th\, 2022\, a fusion experiment at the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory achieved\, for the first time\, a target gain exceeding 1. By imploding a small capsule containing deuterium-tritium fuel with 2.05 MJ of laser light\, the resulting fusion reactions released a total energy of 3.15 MJ of nuclear fusion yield\, thus exceeding the initial input energy. This was the first time for a laboratory experiment to meet the 1997 definition by the National Academy of Sciences of fusion ignition\, an accomplishment six decades in the making. It is the result of focused work by a multi-lab team and required significant advances in high-energy-density physics\, as well as laser\, target\, and diagnostics capabilities. This talk will discuss this momentous result\, the steps that went into achieving it\, and the implications of this achievement for Inertial Fusion Energy. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Christian Reichardt (Melbourne) - Title: Observing the oldest light in the Universe from the South Pole: Gravitational waves\, Neutrinos and more!
DESCRIPTION:Research Progress Meeting \nDate: March 19\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Christian Reichardt (Melbourne) \nTitle: Observing the oldest light in the Universe from the South Pole: Gravitational waves\, Neutrinos and more! \nAbstract: \nThe cosmic microwave background (CMB) radiation is the oldest light we can see. Since it bears the imprint of the universe just after the Big Bang (at a mere 0.003% of the universe’s age today)\, observations of the CMB are a crucial tool in our quest to understand how the Universe began and what its future holds. The South Pole is one of the best sites on Earth for these observations\, and is the home of the South Pole Telescope (as well as CMB-S4 in the future). In this talk\, I will present the latest CMB power spectra measurements from the SPT-3G instrument on the South Pole Telescope\, and the resulting constraints on cosmology. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Tom Shutt (SLAC) - Title: GammaTPC: A novel next generation Compton telescope
DESCRIPTION:Research Progress Meeting \nDate: March 21\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Tom Shutt (SLAC) \nTitle: GammaTPC: A novel next generation Compton telescope \nAbstract: I will talk about GammaTPC\, a new instrument concept for measuring astrophysical gamma rays in the MeV energy range. This part of the sky is a largely unexplored mostly due to the difficulty of measuring MeV photons\, but the potential payoff is large\, particularly in the upcoming era of multi-messenger transient astrophysics. GammaTPC attacks this difficulty using liquid argon time projection chamber (TPC) technology\, which appears to have important advantages over several other techniques that are being pursued. A core part GammaTPC is GAMPix\, a new charge readout scheme that enables fine grained readout over large area at very low power\, and has other potential applications including neutrino physics. There are a few other amusing challenges to fielding a liquid noble TPC in low Earth orbit. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Raphael Flauger (UC San Diego) - Title: Deciphering the Beginning
DESCRIPTION:Research Progress Meeting \nDate: March 26\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Raphael Flauger (UC San Diego) \nTitle: Deciphering the Beginning \nAbstract: \nThe cosmic microwave background (CMB) contains a wealth of information about cosmology as well as high-energy physics. It tells us about the composition and geometry of the universe\, the properties of neutrinos\, dark matter\, and even the conditions in our universe long before the cosmic microwave background was emitted. After a brief introduction\, I will discuss what we may hope to learn about the very early universe from upcoming CMB experiments that search for the imprint of primordial gravitational waves. One of the key challenges of this endeavor is the polarized emission from our galaxy. I will discuss our recent efforts to model and better understand the emission with the help of MHD simulations. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Chiara Salemi (SLAC) - Title: ­­Seeing the invisible: the search for axion dark matter
DESCRIPTION:Research Progress Meeting \nDate: March 28\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Chiara Salemi (SLAC) \nTitle: Seeing the invisible: the search for axion dark matter \nAbstract: The presence of dark matter provides some of the most persuasive evidence for the existence of physics beyond the Standard Model. One compelling dark matter candidate is the axion\, a light boson that was originally postulated as a solution to another outstanding issue\, the strong CP problem in QCD. This talk covers two experimental programs to search for axion dark matter with advanced quantum sensors: DMRadio and BREAD. DMRadio searches for low-mass (long-wavelength) axions using a lumped-element detection method\, while BREAD searches for relatively high-mass (short-wavelength) axions using a reflector. I will discuss the status and upcoming plans for these two programs\, with a focus on the quantum sensors that enable these kinds of searches. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
