David Stuart (UCSB) "Charged particle timing with 30-50 ps resolution in CMS for the high luminosity LHC upgrade"

July 30, 2019 @ 4:00 pm - 5:00 pm

The CMS detector is being upgraded for the phase two of the LHC, where a dataset with much larger integrated luminosity will precisely measure the Higgs boson couplings and extend new phenomena searches to cover challenging scenarios with large backgrounds. Collecting that larger dataset will require much higher instantaneous luminosity causing up to 200 additional proton-proton collisions in each crossing which complicate event reconstruction. A new detector system within this upgrade, the MIP Timing Detector, will provide precise time measurements with 30 to 50 ps resolution for each charged particle. This 4D tracking will resolve the collisions in both space and time, broadly improving the event reconstruction performance. I will describe the motivations for this new detector, its design, and recent progress.
