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

SUMMARY:Speaker: Vladimir Tishchenko (Brookhaven National Laboratory) - Title: The Muon g-2 Experiment: A Precision Test of the Standard Model
DESCRIPTION:Research Progress Meeting \nDate: January 29\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Vladimir Tishchenko\, Brookhaven National Laboratory \nTitle: The Muon g-2 Experiment: A Precision Test of the Standard Model \nAbstract: The anomalous magnetic moment of the muon\, aμ\, is among the most precisely measured quantities in particle physics and a powerful probe of physics within and beyond the Standard Model. 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

SUMMARY:Speaker: Kirit Karkare (Boston University) - Title: On-Chip Millimeter-Wave Spectroscopy for Line Intensity Mapping: SuperSpec and SPT-SLIM
DESCRIPTION:Research Progress Meeting \nDate: February 12\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Kirit Karkare\, Boston University \nTitle: On-Chip Millimeter-Wave Spectroscopy for Line Intensity Mapping: SuperSpec and SPT-SLIM \nAbstract: Answering outstanding questions in cosmology – such as understanding the nature of inflation\, dark energy\, and reionization – requires observations of ever-increasing volumes of the universe. 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

SUMMARY:Speaker: Jamie Bock (JPL) - Title: Spectrally Mapping the Sky with SPHEREx
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

SUMMARY:Speaker: Jason Rhodes (JPL) - Title: Mapping the Dark Universe with Euclid
DESCRIPTION:Research Progress Meeting \nDate: February 26\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jason Rhodes (JPL) \nTitle: Mapping the Dark Universe with Euclid \nAbstract: After 2 decades of preparation\, the European Space Agency’s Euclid space telescope was launched on July 1\, 2023. Euclid’s primary goal is to study the dark universe and help us better understand the enigmatic dark matter and dark energy that make up the bulk of the universe. I will talk about my personal journey in bringing Euclid to fruition\, give the details of the Euclid telescope and instruments that make it so powerful as a dark energy probe\, talk about the science that came out of Euclid’s 60 square degree data release in 2025\, plans for science with Euclid’s ~2000 square degree data release in late 2026 and Euclid’s eventual full data release of 14\,000 square degrees. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Calvin Leung (UC Berkeley) - Title: From Radio Interferometry to Astrophysics and Cosmology using Fast Radio Bursts
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: Thomas Essinger-Hileman (NASA Goddard) - Title: Science with CLASS and Future CMB Space Missions
DESCRIPTION:Research Progress Meeting \nDate: April 16\, 2026 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Thomas Essinger-Hileman (NASA Goddard) \nTitle: Science with CLASS and Future CMB Space Missions \nAbstract: The cosmic microwave background (CMB) is a unique probe of the state of the early universe and its evolution since recombination approximately 380\,000 years after the Big Bang. CMB observations have been critical in building a concordance model of cosmology consisting of a spatially flat universe dominated by dark matter and dark energy. Current CMB projects from the ground and balloons continue to address fundamental questions in astrophysics\, cosmology\, and particle physics: Did cosmic inflation create our Universe? What is the nature of dark energy? When and how did the first stars reionize the universe? and What is the mass of the neutrinos? I will highlight ongoing work to constrain reionization and the mass of neutrinos with the Cosmology Large Angular Scale Surveyor (CLASS)\, which observes more than 65% of the sky from the Atacama Desert of Chile\, as well as need for future CMB space missions like LiteBIRD and a NASA CMB Probe satellite to make the ultimate measurements of the CMB at large angular scales. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
