SUMMARY:Maria Mironova (Oxford)  “First Direct Constraint on the Higgs-Charm Coupling and its Expected Evolution with the ATLAS Detector Upgrade”
DESCRIPTION:Abstract:
 \nThe coupling of the Higgsboson to charm quarks has eluded experimental observation since the Higgs boson discovery in 2012. At present\, this is the largest contribution to possibleHiggs boson decays that is not experimentally verified. However\, this measurement is crucial to shed light on the fundamental coupling of the Higgs boson to second-generation quarks. This seminar highlights the recent search for Higgs boson decays into a pair of charm quarks\, produced in association with a vector boson\, using the data collected by the ATLAS detector between 2015 and 2018.This measurement sets the first direct limit on the Higgs boson coupling to charm quarks \nWith the upgrade to High-Luminosity LHC (HL-LHC)\, a significant improvement to this measurement is expected due to the increased size of the dataset as well as the upgrade of the ATLAS Inner Tracker (ITk). A new pixel detector system will improve resolution\, increasing the identification efficiency of charm quarks. However\, the detector will have to cope with higher data rates and withstand higher levels of radiation. The ITk pixel upgrade\, particularly the characterisation of the pixel readout chips\, and the expected precision of the measurement of the Higgs boson coupling to charm quarks at the HL-LHC are discussed. \n \n \n──────────\nTroy Cortez is inviting you to a scheduled Zoom meeting.\n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/99938871022?pwd=YjZ5azNyaUtVV2FVTWNEZkJUTmc4Zz09\n\nMeeting ID: 999 3887 1022\nPasscode: 872514\nOne tap mobile\n+16699006833\,\,99938871022#\,\,\,\,*872514# US (San Jose)\n+12532158782\,\,99938871022#\,\,\,\,*872514# US (Tacoma)\n\nDial by your location\n        +1 669 900 6833 US (San Jose)\n        +1 253 215 8782 US (Tacoma)\n        +1 346 248 7799 US (Houston)\n        +1 646 558 8656 US (New York)\n        +1 301 715 8592 US (Washington DC)\n        +1 312 626 6799 US (Chicago)\nMeeting ID: 999 3887 1022\nPasscode: 872514\nFind your local number: https://lbnl.zoom.us/u/aeEwdvaKic\n\nJoin by SIP\n99938871022@zoomcrc.com\n\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 (Amsterdam Netherlands)\n213.244.140.110 (Germany)\n103.122.166.55 (Australia Sydney)\n103.122.167.55 (Australia Melbourne)\n64.211.144.160 (Brazil)\n69.174.57.160 (Canada Toronto)\n65.39.152.160 (Canada Vancouver)\n207.226.132.110 (Japan Tokyo)\n149.137.24.110 (Japan Osaka)\nMeeting ID: 999 3887 1022\nPasscode: 872514\n\n\n──────────
