SUMMARY:Speaker: Eric Torrence (University of Oregon)- Title: Precision Luminosity with the ATLAS Experiment
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 25\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSPEAKER: Eric Torrence (University of Oregon) \nTITLE: Precision Luminosity with the ATLAS Experiment\n \nABSTRACT: Abstract:  A precise measurement of the integrated luminosity is a key component of the ATLAS physics program at the CERN LHC. This measurement is based on an absolute calibration of the LUCID detector using dedicated van der Meer beam-separation scans\, and extrapolated to physics conditions with a set of complimentary measurements from the ATLAS inner detector and calorimeter systems. Evaluated for all physics data recorded during the LHC Run2 data taking (from 2015-18)\, the uncertainty on the integrated luminosity delivered to ATLAS has achieved a relative precision of 0.8%. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:[SPECIAL RPM] Speaker: Marcel Vos (IFIC (UV/CSIC) Valencia)
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 22\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSpeaker: Marcel Vos (IFIC (UV/CSIC) Valencia) \nTitle: “The third-generation quarks and the Higgs boson – from the LHC to the next large-scale facility in HEP” \nAbstract: In this seminar I discuss a number of selected topics in studies of the bottom and top quarks. A few recent highlights of the top quark physics program of the ATLAS and CMS experiments at the LHC are presented. These results continue to improve the precision that can be achieved at a hadron collider and expand the energy frontier beyond several TeV. An extensive search program open ups increasingly rare top quark production processes\, providing access to couplings that had not been tested directly so far. To provide a broader perspective\, current results are compared to the prospects of the High Luminosity phase of the LHC and of a future electron-positron collider. The seminar finalizes with a discussion of a proposal to use the interactions of the bottom (and top) quarks with the Higgs boson to test the evolution of particle masses with energy predicted by the Standard Model. \n\nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/96855892866?pwd=dEltOWdIdHZSSHlBRGJiUXlQdm1Pdz09 \nMeeting ID: 968 5589 2866\nPasscode: 915719

SUMMARY:Speaker: Frank Qu (Cambridge University) - Title: Cosmology from high-precision CMB lensing measurements with the Atacama Cosmology Telescope
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 18\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSPEAKER: Frank Qu (Cambridge University) \nTITLE: Cosmology from high-precision CMB lensing measurements with the Atacama Cosmology Telescope \nABSTRACT: \nThe cosmic microwave background provides a unique backlight for illuminating the growth of structures in our universe. Measuring the arcminute-scale lensing deflections experienced by the CMB photons as they travel to our telescopes enables the mapping of the matter distribution to very high redshifts. This lensing signal provides a clean window for constraining fundamental physics\, such as the sum of neutrino masses\, and enables powerful tests of the standard cosmological model via comparison of high-precision measurements of structure growth at late times with early-time predictions. \n  \nIn this talk\, I will present new CMB lensing measurements derived from data release 6 of the Atacama Cosmology Telescope. Our work provides a state-of-the-art lensing power spectrum measurement and an associated signal-dominated lensing mass map that enable a host of cosmological and astrophysical science goals. I will first discuss the novel methods used to tackle key systematics affecting precision CMB lensing. I will then explore the implications of our measurements for tests of cosmic structure growth and the S8 tension. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:Speaker: Stefania Gori (UCSC)-Title: New meson probes of axion-like-particles
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: MAY 2\, 2023 \nLocation: Sessler Conference Room – 50A-5-5132 \nSpeaker: Stefania Gori (UCSC) \nTitle: New meson probes of axion-like-particles \nAbstract: \n\nMeson factories are at the cutting edge of the intensity frontier\, with an unprecedented number of pions\, Kaons\, and B mesons that will be produced in the coming years. In addition to precise measurements of Standard Model processes\, these experiments have a unique opportunity to search for dark sector particles in the sub-GeV mass range. In this talk\, we will first give an overview of new opportunities to search for axion-like particles (ALPs) in light meson decays. Such ALPs can be motivated by a solution to the hierarchy problem\, the strong CP problem\, the flavor puzzle\, and combinations of these with DM physics.  Second\, we revisit the theory and constraints on ALPs interacting with leptons\, pointing out the relevance of charged current meson and W decays to ALPs. This is particularly prominent in models where the ALP couples in an isospin-violating way. Finally\, we highlight the role of the future PIONEER experiment in probing these new charged current pion decays to ALPs.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182\nPasscode: 169037

SUMMARY:Speaker: Gabriel Orebi Gann\, (UCB/LBNL)- Title: Let There be Light: next-generation neutrino detection at Theia
DESCRIPTION:This is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: April 27\, 2023 \nTIME: 4:00 PM \nTITLE: Let There be Light: next-generation neutrino detection at Theia \nABSTRACT: Neutrinos are some of the most fascinating particles that occur in nature. Over one billion times lighter than the proton\, the neutrino was once thought to be massless and to travel at the speed of light. The Nobel-Prize winning discovery of neutrino oscillations demonstrated that neutrinos have non-zero mass\, which opens up the unique possibility of the neutrino being its own antiparticle\, known as a Majorana fermion. This talk will discuss the physics landscape\, and present recent technological advances that enable a new kind of “hybrid” neutrino experiment\, which would combine two highly successful detection techniques: the topological information of Cherenkov detectors\, with the high light yield of scintillators. The Theia detector would be capable of combining both signals to achieve unprecedented levels of particle and event identification\, offering a rich program of science across high-energy particle\, nuclear and astrophysics. If deployed as one of the “modules of opportunity” at the DUNE far site\, Theia could offer insights into both CP violation\, and the search for Majorana neutrinos: the two ingredients necessary to shed light on the source of the matter antimatter asymmetry in our Universe. \nZOOM INFORMATION – \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:Speaker: Bruce Macintosh Title: Direct imaging of extrasolar planets- Thursday\, April 20 at 4pm
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: Thursday\, April 20\, 2023 \nLocation: Sessler Conference Room- 50A-5132 \nTime: 4:00- 5:00 pm \nSpeaker: Bruce Macintosh \nTitle: Direct imaging of extrasolar planets\n \nAbstract: Direct detection of extrasolar planets – spatially resolving a planet from its host star while blocking\, moving\, or post-processing the starlight – is a powerful complement to transit\, RV\, and microlensing approaches. Direct detection is sensitive to planets in wider orbit\, and allows spectroscopic characterization of planetary atmosheres. One of the most effective instruments in this regime has been the Gemini Planet Imager (GPI). GPI was a facility instrument combining advanced adaptive optics\, a diffraction-controlling coronagraph\, and an infrared integral field spectrograph on the Gemini South Telescope. From 2014-2019 we carried out the Gemini Planet Imager Exoplanet Survey (GPIES)\, which observed 532 young (10-200 Myr) nearby stars. I will describe the instrument\, summarize the key results of the GPIES program\, including constraints on giant-planet distributions and atmospheric properties. We have also extensively characterized GPI’s performance\, leading to insights into next-generation systems. \nWith current technology\, direct imaging with GPI or other instruments is sensitive primarily to planets that are significantly younger than\, more massive than\, and in wider orbits than Jupiter\, and such planets are rare. Moving beyond this will require new capabilities. The GPI 2.0 project upgrades the existing instrument with faster adaptive optics\, better coronagraph designs\, and new spectrograph modes.When deployed on Gemini North\, GPI 2.0 will be able to search younger stars in the Taurus and Ophiucus star-forming regions\, and be sensitive to Jupiter-like “cold start” planets. I will summarize the science drivers that guided the GPI 2.0 upgrade and the project’s status.\n \n\nZoom Information \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:Speaker: Cristiano Sebastiani- Title: "Search for exotic physics with long-lived particles at ATLAS "
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: April 18\, 2023 \nLocation: INPA Conference Room- 50-5026 \nTime: 4:00- 5:00 pm \nSpeaker: Cristiano Sebastiani \nTitle: Search for exotic physics with long-lived particles at ATLAS\n \nAbstract: Exotic long-lived particles (LLPs) could provide valuable insights into the nature of Dark Matter (DM) and represent a potential extension to the Standard Model (SM) of particle physics. However\, Large Hadron Collider (LHC) search programs may have overlooked LLPs due to their unique features\, which are often dismissed as noise. Decay of LLPs outside of the interaction region gives rise to striking signatures\, such as late calorimetric energy deposits\, displaced vertices\, and long time-of-flight. This presentation focuses on the current status and experimental challenges of searching for LLPs with the ATLAS detector\, with an emphasis on innovative techniques used to improve sensitivity. Lastly\, this presentation will discuss the prospects for the LLP programme at CERN in the future.\n \n\nZoom Information \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/93563368865?pwd=dUVWd1ZWc2ZQenFmdGVuejBEZE03UT09 \nMeeting ID: 935 6336 8865\nPasscode: 157411

SUMMARY:Speaker: Dave Moore (Yale)-Title: Optomechanical sensors for nuclear and particle physics
DESCRIPTION:This is an In-Person [HYBRID] Event \nDate: April 13\, 2023 \nLocation: Sessler Conference Room- 50A-5132 \nTime: 4:00- 5:00 pm \nSpeaker: Dave Moore (Yale) \nTitle: Optomechanical sensors for nuclear and particle physics \nAbstract: The development of optomechanical systems has revolutionized the detection of tiny forces over the past few decades. As such technologies reach (and surpass) quantum measurement limits\, they can enable new searches for weakly coupled phenomena\, including dark matter\, gravitational waves\, “fifth’’ forces\, and sterile neutrinos. As a demonstration of these techniques\, I will describe an initial search for dark matter using an optically levitated nanogram mass sensor\, which can exceed the sensitivity of even large underground detectors for certain classes of dark matter candidates in a few days of exposure. If a signal were detected\, such sensors would also be able to correlate its direction with earth’s motion through the galaxy\, allowing definitive confirmation that such a signal arose from dark matter. The same techniques can also permit new laboratory searches for sterile neutrinos\, potentially probing orders-of-magnitude smaller mixings with active neutrinos than previous experiments in the keV-MeV mass range. I will describe recent proposals to perform such searches using optically trapped nanoparticles doped with beta emitters.\n \n\nZoom Information \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:Speaker: Adam Miller ( Northwestern)- TITLE:  Red after Dead – Understanding the Progenitors of "Cool" Explosions
DESCRIPTION:This is an In-Person [HYBRID] Event \nLocation: Sessler Conference Room- 50A-5132 \nTitle:  Red after Dead – Understanding the Progenitors of “Cool” Explosions\n \nAbstract: In this talk I will discuss open questions in our quest to develop a map between progenitor systems and supernova explosions. Solving the puzzle has important ramifications for understanding the chemical enrichment of the Universe and galactic evolution and feedback. I will highlight Type Ia supernovae and discuss an exquisite set of observations obtained by the Zwicky Transient Facility (ZTF). From the early observations we can constrain the progenitors\, and we have recently identified a new subclass of peculiar Type Ia supernovae that comes from a unique progenitor channel. To close I will discuss a new project\, the La Silla Southern Sky Survey (LS4). LS4 is upgrading the Quest camera to fill the 20 sq. deg. focal plane with red-sensitive LBNL CCDs to conduct a new time-domain survey. This instrument is uniquely sensitive to red transients in the local universe\, including (hopefully) the optical counterparts to gravitational wave events. \nZoom Information \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239\nOne tap mobile

SUMMARY:EVENT CANCELED: SPEAKER: Gabriel Orebi Gann (LBNL)-TITLE: Let There be Light: next-generation neutrino detection at Theia
DESCRIPTION:EVENT CANCELED \nThis is an In-Person [HYBRID] Event \nLOCATION: Sessler Conference Room – 50A – 5132 \nDATE: March 16\, 2023 \nTIME: 4:00 PM \nTITLE: Let There be Light: next-generation neutrino detection at Theia \nABSTRACT: Neutrinos are some of the most fascinating particles that occur in nature. Over one billion times lighter than the proton\, the neutrino was once thought to be massless and to travel at the speed of light. The Nobel-Prize winning discovery of neutrino oscillations demonstrated that neutrinos have non-zero mass\, which opens up the unique possibility of the neutrino being its own antiparticle\, known as a Majorana fermion. This talk will discuss the physics landscape\, and present recent technological advances that enable a new kind of “hybrid” neutrino experiment\, which would combine two highly successful detection techniques: the topological information of Cherenkov detectors\, with the high light yield of scintillators. The Theia detector would be capable of combining both signals to achieve unprecedented levels of particle and event identification\, offering a rich program of science across high-energy particle\, nuclear and astrophysics. If deployed as one of the “modules of opportunity” at the DUNE far site\, Theia could offer insights into both CP violation\, and the search for Majorana neutrinos: the two ingredients necessary to shed light on the source of the matter antimatter asymmetry in our Universe. \nZOOM INFORMATION – \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239

SUMMARY:SPEAKER: John Groh (NIST)- TITLE: Pointing Superconductors at the Sky: Towards new fundamental physics through precision cosmic microwave background measurements
DESCRIPTION:This is an In-Person Event \nLocation: Sessler Conference Room – 50A-5-5132 \nTitle: Pointing Superconductors at the Sky: Towards new fundamental physics through precision cosmic microwave background measurements \nAbstract: The cosmic microwave background is an incredible tool for probing fundamental physics\, both as a snapshot of the early universe and as a backlight to subsequent cosmic evolution. The next generation of observatories will cross several important qualitative thresholds for characterizing possible cosmic inflation mechanisms and neutrino masses while also constraining dark energy\, light relic particles\, and modified gravity. To make these measurements\, these observatories will require at least an order of magnitude improvement in both sensitivity and size\, presenting significant instrumentation challenges. In this talk\, I will discuss key technology advances leading to more capable instruments\, focusing on highly multiplexed readout of the increasingly large cryogenic sensor arrays. I will also describe work incorporating novel instrumentation technologies into a new microwave observatory – the Simons Array – and commissioning it at its observing site in the Chilean Atacama. Not only are these developments enabling new physics and cosmology measurements through the Simons Array\, SPT-3G\, the Simons Observatory\, and AliCPT experiments\, but they are also building technological readiness as the field prepares for CMB-S4. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239 \n

SUMMARY:SPEAKER: Clara Verges (Harvard)- TITLE: A window on the Universe with the next-generation of millimeter-wave telescopes
DESCRIPTION:This is an In-Person Event \nLocation: Sessler Conference Room – 50A-5-5132 \nTitle: A window on the Universe with the next-generation of millimeter-wave telescopes \nAbstract: Cosmology 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 second after the Big Bang to unveiling the dark Universe and 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 technological challenges that the CMB community must meet to ensure the scientific success of future experiments. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 988 5432 2464 \nPasscode: 142239

SUMMARY:Speaker: Sara Simon (Fermilab)-Title: Precision Cosmology with the Cosmic Microwave Background
DESCRIPTION:This is an In-Person Event \nLocation: Sessler Conference Room – 50A-5-5132 \nTitle: Precision Cosmology with the Cosmic Microwave Background \nAbstract: The cosmic microwave background (CMB) provides an unparalleled opportunity to advance our understanding of the fundamental physics of the universe. Recent and ongoing experiments have contributed to our understanding of neutrinos\, dark energy\, and dark matter through measurements of large-scale structure imprinted on the CMB and constrained the conditions in the early universe\, tightly restricting inflationary and other cosmological models through measurements of CMB polarization. Next-generation CMB experiments like CMB-S4 will further constrain the sum of the neutrino masses and the number of relativistic species\, expand our understanding of dark energy and dark matter\, and set new constraints on cosmological models describing the first moments of the universe. The polarization in the CMB is faint\, so future experiments must be at least an order of magnitude more sensitive than current experiments. These unprecedented levels of sensitivity require improved systematic mitigation via modeling and novel calibration techniques. I will give an overview of the science achievable with these next-generation experiments and the advances in technology that are critical for its this leap in performance. \nZoom Information \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 988 5432 2464 \nPasscode: 142239

SUMMARY:SPEAKER: Steve Choi (Cornell)- TITLE: Probing fundamental physics by mapping the millimeter and submillimeter sky
DESCRIPTION:This is an In-Person Event \nLocation: Sessler Conference Room – 50A-5-5132 \nTitle: Probing fundamental physics by mapping the millimeter and submillimeter sky \nAbstract: Cosmology has transformed from a field of speculation to precision science as a result of a wealth of data from sensitive instruments. In particular\, precise observations of the cosmic microwave background (CMB) have revolutionized our understanding of the Universe. Despite the success of the standard model of cosmology (ΛCDM) in describing much of the cosmos with just six parameters\, many fundamental questions remain unresolved. Are there primordial gravitational waves? Are there new light relic particles? How will the current cosmological tensions be resolved? Improved mapping of the millimeter and submillimeter sky will help address these questions. I will highlight recent results from the Atacama Cosmology Telescope (ACT)\, and describe how the new ACT maps will advance our understanding of the Universe beyond Planck. I will also present recent progress on CCAT-prime and Simons Observatory that are paving the way for CMB-S4 in pursuit of next-generation cosmology. \nZoom Information \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:SPEAKER: Dan Carney (LBNL) - TITLE: The End of Measurement and The Last Lab
DESCRIPTION:This is an In-Person Event \nLocation: Sessler Conference Room- 50A-5132 \nTitle: The End of Measurement and The Last Lab \nAbstract: I will give a breezy overview–designed to be provocative and hopefully enjoyable–of the way quantum mechanical noise enters a number of “holy grail” experimental targets in HEP. The recent theoretical observation that PTOLEMY as designed cannot actually detect relic neutrinos\, due to Heisenberg uncertainty in the tritium target\, will serve as an opening cautionary tale. I will then explain how one could in principle circumvent this problem\, and use this as a springboard to discuss a few other possible experiments: measurement of the neutrino mass using a PTOLEMY-esque scheme\, detection of “single gravitons” and/or gravitational entanglement\, and finally the direct detection of ultraheavy dark matter purely through its gravitational interaction.\nThese examples are chosen to motivate the core idea: the fundamental limits imposed by quantum mechanical noise are still broadly unknown\, and a great deal of work is still needed to both identify these limits theoretically and engineer devices that can approach them. \nZOOM INFORMATION –  \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464 \nPasscode: 142239 \n  \n  \n

DESCRIPTION:This is an in-person Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Excitement and Challenges with Multiplexed Spectroscopic Galaxy Surveys \nABSTRACT: \nThe ongoing Dark Energy Spectroscopic Instrument (DESI) Survey is collecting galaxy redshifts at an astounding rate. Analysis from this new data promises exciting new constraints on big cosmological problems such as dark energy models and primordial non-gaussianity along with a measurement of the sum of the neutrino masses. Key technologies including the robotic focal plane system help enable nearly 5\,000 simultaneous spectra with on average 2 minutes between exposures. In this talk I will describe some of the challenges encountered optimizing the DESI instrument for science results. Furthermore\, I will discuss some of the impact the focal plane and fiber assignment algorithms have on galaxy clustering data and some novel mitigations I am exploring to resolve this problem. Finally\, I will conclude with a look to the future and how we can engage in current efforts to build on the success of DESI. \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585

SUMMARY:SPEAKER: Josephine Paton – University of Oxford – TITLE: Directional Neutrino Measurements in Liquid Scintillators
DESCRIPTION:This is a VIRTUAL Event \nLocation: Sessler Conference Room – 50A-5132 \nTITLE: Directional Neutrino Measurements in Liquid Scintillators \nABSTRACT: \nNeutrinos are one of the most enigmatic particles in the Standard Model. Precise measurements of their properties are vital for our understanding of the subatomic world\, and may bring us closer to answering questions such as “Why do neutrinos have mass?” and “Why is the universe matter dominated?”. In order to do this\, novel technologies and methodologies are being developed to extract as much information as possible from the interactions of neutrinos on matter. \nLiquid scintillators have been utilised in neutrino detectors for decades\, benefitting from a high light yield which leads to precise energy reconstruction. However\, scintillation light is isotropic\, meaning scintillator detectors do not benefit from the directional information used in Cherenkov-based neutrino detectors. Significant investment has been put into developing new methods to extract Cherenkov information from scintillation signals\, allowing for a combination of energy precision and directional background rejection. In this talk I outline the methods developed for directional reconstruction in the SNO+ experiment\, and present the first demonstration event-by-event directionality of solar neutrinos in a high yield scintillator. \nZOOM Information – \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/91782268585\nMeeting ID: 917 8226 8585
