SUMMARY:Lina Necib (Caltech) "Dark Matter in the Era of Gaia"
DESCRIPTION:ABSTRACT: \nThe Gaia mission has provided distance and velocity measurements of over a billion stars in the Milky Way\, making it the largest stellar catalog at hand. Simultaneously\, recent developments in cosmological simulations have made it possible to track stars and dark matter in realistic Milky Way-like galaxies. In this talk\, I will demonstrate how using cutting-edge simulations and Gaia data in tandem has enabled me to start building the first local map of the cold dark matter phase space distribution in our Galaxy. Doing so led me to discover Nyx\, a stream of stars in the solar neighborhood that I identified using machine learning methods. Nyx\, potentially the result of a prograde merger\, is crucial in understanding the formation of the disk of the Milky Way as it might have been associated with an accreted dark disk. Finally\, I will summarize how future surveys will help fully map out the phase space distribution of dark matter in the Milky Way\, and show that such an empirical map will have extensive ramifications for dark matter searches. \n\n\n\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/629888022Meeting ID: 629 888 022 \nOne tap mobile\n+16699006833\,\,629888022# US (San Jose)\n+13462487799\,\,629888022# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\n+1 301 715 8592 US\nMeeting ID: 629 888 022\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n629888022@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 629 888 022 \n──────────

SUMMARY:Rodrigo Alonso (Durham U) "Geometry for Higgs Dynamics and Effective Field Theory"
DESCRIPTION:Abstract:\n\nThe three Nambu-Goldstone bosons in the longitudinal modes of the W and Z  together with the Higgs boson span a 4-dimensional manifold. The geometry of this manifold\, invariant under field re-parametrization\, encodes the scalar dynamics which are vastly unexplored at present. The small but finite curvature limit recovers the Standard Model and  corrections in its effective field theory. First order corrections in this framework encode widely different physics and serve to test and constrast the different facets of the SM and their correlation. \n\nhttp://physics.lbl.gov/rpm/index.php/events/\n\nIf you are looking to confirm if there is an event\, due to room reservation\, please go to RPM website for a list of all scheduled talks.\n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/195991343 \nMeeting ID: 195 991 343 \nOne tap mobile\n+16699006833\,\,195991343# US (San Jose)\n+13462487799\,\,195991343# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 301 715 8592 US\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\n+1 253 215 8782 US\nMeeting ID: 195 991 343\nFind your local number: https://lbnl.zoom.us/u/acBxMxIpwT \nJoin by SIP\n195991343@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n221.122.88.195 (China)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n209.9.211.110 (Hong Kong)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 195 991 343 \n────────── \n

SUMMARY:Seljak\, Modi\, Boehm (RPM)
DESCRIPTION:Uros Seljak\, Chirag Modi\, Vanessa Boehm (LBL/Berkeley)\nHow deadly is COVID-19?  A time series analysis of Italy mortality data\n\nAbstract:\n\nA counterfactual analysis of 2020 mortality data reported from towns in Italy\, with data from the previous five years as control\, reveals a large excess of deaths in March 2020. The analysis shows a good agreement with reported COVID-19 mortality for age<70 years\, but an excess in total mortality increasing with age above 70 years\, suggesting there is a large population of predominantly old people missing from  the official fatality statistics. We estimate that the number of COVID-19 deaths in Italy is 52\,000 $\pm$ 2000 as of April 18 2020\, more than a factor of 2 higher than the official number. We determine infection fatality rate (IFR) lower bound of 0.84% for Lombardia and infection rate of 23% for Lombardia\, a factor of 35 above the number of positive tests. The infection rate for Bergamo province is 63%\, suggesting herd immunity has been reached there. The analysis can help predict corresponding numbers in USA: we predict 0.5% lower bound on IFR for NYC and Santa Clara county. We observe that the COVID-19 mortality tracks closely the overall mortality of the underlying population\, explaining why we see so many more deaths below age of 65 as a fraction of total in NYC relative to Italy. \nSlides \nWatch Video

SUMMARY:RPM - Physics Division | Ben Nachman (LBNL) "Gearing up for the 2021 APS DPF Community Planning Process (aka Snowmass)" https://lbnl.zoom.us/j/95017728528
DESCRIPTION:Abstract: \n\nThe American Physical Society’s Division of Particles and Fields is gearing up for its next community planning process (for historical reasons\, called Snowmass).  This process will occur over the next year and culminate in a 10 year plan (with a 20 year vision) for the future.  It is critical for us to provide input to this process\, which will ultimately inform the funding agencies about our community’s priorities for the future.  In this talk\, I will briefly introduce the various frontiers of the 2021 Snowmass process and will then mostly focus on the Computational Frontier and its connection to the other frontiers.  In particular\, this is an interesting time for computation with significant big data tools and infrastructure being developed by the broader scientific and industrial communities and with the advent of new (not part of the last Snowmass!) technologies like deep learning and quantum computing.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95017728528 \nMeeting ID: 950 1772 8528\nOne tap mobile\n+12532158782\,\,95017728528# US (Tacoma)\n+13017158592\,\,95017728528# US (Germantown) \nDial by your location\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 346 248 7799 US (Houston)\n+1 646 558 8656 US (New York)\n+1 669 900 6833 US (San Jose)\nMeeting ID: 950 1772 8528\nFind your local number: https://lbnl.zoom.us/u/adExQ72UHW \nJoin by SIP\n95017728528@zoomcrc.com \nJoin by H.323\n162.255.37.11 (US West)\n162.255.36.11 (US East)\n115.114.131.7 (India Mumbai)\n115.114.115.7 (India Hyderabad)\n213.19.144.110 (EMEA)\n103.122.166.55 (Australia)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada)\n207.226.132.110 (Japan)\nMeeting ID: 950 1772 8528 \n──────────
