SUMMARY:Nan Lu (Caltech) "Evidence for Higgs Boson Decay to a Pair of Muons from the CMS Experiment "
DESCRIPTION:Abstract:\n\nThis seminar presents the search for the rare Higgs boson decay to a pair of muons performed by the CMS experiment at the LHC\, based on the full Run 2 dataset. Events are categorized based on the characteristics of major Higgs boson production mechanisms and are analyzed using machine learning techniques\, which significantly boosts the sensitivity of the search. A 3.0σ excess is observed in data\, constituting the first evidence for the Higgs boson coupling to muons. \n\n\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/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@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: 917 8226 8585 \n──────────

SUMMARY:Andrej Obuljen (Waterloo) "Anisotropic Assembly Bias in Theory\, Simulations and BOSS Data"
DESCRIPTION:ABSTRACT\nClustering of matter on large scales provides an important source of information on key cosmological parameters. To extract this information we need to understand the relation between the tracers we observe and the underlying matter field. The clustering strength of halos and galaxies on large scales is linearly biased compared to the matter clustering. This linear bias mainly depends on halo mass and redshifts\, though selections based on other scalar halo properties (age\, spin\, concentration etc.) show additional bias dependences — called assembly bias. Furthermore\, non-scalar halo properties: shapes\, velocity dispersion and angular momentum\, are correlated with the large-scale tidal field. Selection effects that couple to these non-scalar halo properties can produce anisotropic clustering even in real-space and act as a contaminant to redshift-space distortion measurements\, through an anisotropic assembly bias (AB). I will discuss our recent results on studying the halo AB using a large number of numerical simulations. Then I will present the first detection of the galaxy anisotropic assembly bias in BOSS DR12 galaxies. Finally\, I will show other consequences and future prospects. \nhttp://physics.lbl.gov/rpm/index.php/events/\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/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@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: 917 8226 8585 \n──────────

SUMMARY:Simone Pagan-Griso (LBNL) "The Future of the Energy Frontier: Highlights from the Snowmass 2021 Process"
DESCRIPTION:Abstract: \nThe Snowmass process is an opportunity for the entire HEP community to come together to identify and document a vision for the future of particle physics in the U.S. and its international partners. The Snowmass 2021 process is currently ongoing and scheduled to deliver a report in the fall of 2021. The work is divided in many areas (frontiers)\, spanning collider-based physics\, neutrino physics\, and cosmology\, but including dedicated theory and instrumentation areas as well.\nIn this seminar\, I will focus on highlighting some of the ideas and plans that have been forming in the area of the energy frontier\, with particular focus on prospects for direct searches of Beyond-Standard-Model physics; I will also discuss some synergies with other areas\, when relevant.

SUMMARY:Hannsjörg Weber (FNAL) "Triple Threat: The Observation of Tribosons "
DESCRIPTION:Hannsjörg Weber \nTriple Threat: The observation of tribosons \nAbstract: \nWe present the search for heavy triboson production\, specifically targeting the production of WWW\, WWZ\, WZZ and ZZZ processes in multileptonic final states with 137/fb of data collected by the CMS detector during Run II of the LHC at a center-of-mass energy 13 TeV.  The search is performed in final states with three\, four\, five\, and six leptons (electrons or muons)\, or with two same-charge leptons plus two jets. \nDuring this seminar\, the physics behind the triboson process will be motivated\, including a discussion on the difficulties to experimentally measure it. Then\, the analysis strategy aimed to observe tribosons will be shown and the results will be presented. At the end\, an outlook on future triboson studies and extensions towards probing the standard model and potential new physics will be given. \n \nhttp://physics.lbl.gov/rpm/index.php/events/\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/95906405235 \nMeeting ID: 959 0640 5235\nOne tap mobile\n+16699006833\,\,95906405235# US (San Jose)\n+13462487799\,\,95906405235# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 959 0640 5235\nFind your local number: https://lbnl.zoom.us/u/a9dnGtb5T \nJoin by SIP\n95906405235@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: 959 0640 5235 \n──────────

SUMMARY:Donatella Lucchesi (INFN) ""Muon Collider: A Window to the Future""
DESCRIPTION:Abstract:\n \nMuon colliders represent a highly attractive option for future collider thanks to the possibility to reach very high center of mass energy\, high luminosity with reasonable costs and dimensions. Nevertheless\, the feasibility is not yet fully demonstrated and presents several challenges: muon beams production and operations from the machine side and beam-induced background mitigation on the detector part. Several progress have been achieved in the last years allowing to re-open the muon collider case. The detailed study of the beam-induced background has demonstrated that even the most challenging events like those involving b-jets can be efficiently reconstructed. This has triggered the study of several Higgs related processes in particular the double and triple Higgs production with sufficient precision to fully determine the Higgs potential. In the seminar a brief description of the machine will be followed by a discussion on the performance on detector and Higgs reconstruction. \n \nhttp://physics.lbl.gov/rpm/index.php/events/\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/91782268585 \nMeeting ID: 917 8226 8585\nOne tap mobile\n+16699006833\,\,91782268585# US (San Jose)\n+13462487799\,\,91782268585# US (Houston) \nDial by your location\n+1 669 900 6833 US (San Jose)\n+1 346 248 7799 US (Houston)\n+1 253 215 8782 US (Tacoma)\n+1 646 558 8656 US (New York)\n+1 301 715 8592 US (Germantown)\n+1 312 626 6799 US (Chicago)\nMeeting ID: 917 8226 8585\nFind your local number: https://lbnl.zoom.us/u/abeLb1T4q1 \nJoin by SIP\n91782268585@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: 917 8226 8585 \n──────────
