SUMMARY:Emily Ann Thompson (DESY) "The Quest For Long-Lived Particles: Searching For Displaced Vertices and Tracking in the Trigger"
DESCRIPTION:Abstract: \nThe existence of long-lived particles (LLPs) is a common feature in many theories beyond the Standard Model. For example\, models with small couplings (i.e. R-parity-violating supersymmetry) and models with compressed mass spectra (i.e. co-annihilating dark matter) predict the presence of LLPs. With lifetimes ranging from picoseconds to nanoseconds\, massive LLPs could decay to several electrically charged particles in the inner tracking volume of the ATLAS detector\, resulting in the reconstruction of a displaced secondary vertex. Integrating tracking information into the trigger at an early stage is critical to enhancing the sensitivity of future searches for LLPs with displaced track signatures. The ATLAS Fast TracKer (FTK) aimed to achieve this by performing global\, hardware-based track finding at a trigger rate of 100 kHz. \nIn this talk\, searches for new long-lived massive particles leaving a displaced vertex signature in the ATLAS inner detector with the full Run-2 dataset are presented. Furthermore\, the FTK system is presented and its application to LLP searches is discussed. \n  \n  \n\n\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/92777524053?pwd=Z1JFbVhtZE9jMW1DcnJrd0svU1A4UT09 \nMeeting ID: 927 7752 4053\nPasscode: 509215\nOne tap mobile\n+16699006833\,\,92777524053#\,\,\,\,*509215# US (San Jose)\n+13462487799\,\,92777524053#\,\,\,\,*509215# 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 (Washington DC)\n+1 312 626 6799 US (Chicago)\n+1 646 558 8656 US (New York)\nMeeting ID: 927 7752 4053\nPasscode: 509215\nFind your local number: https://lbnl.zoom.us/u/aeM3Tnxfb \nJoin by SIP\n92777524053@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 (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: 927 7752 4053\nPasscode: 509215 \n──────────
