High Energy Experiment Seminar: Track-triggering at CMS for the High-Luminosity LHC

Louise Skinnari (Northeastern University)

The high luminosity upgrade of the Large Hadron Collider (LHC), scheduled for 2025-2027, will significantly increase the instantaneous luminosity of the LHC collisions. The resulting large proton-proton collision datasets will allow precise measurements of Higgs boson properties, searches for very rare processes, and much more. To cope with the challenging experimental environment resulting from the high luminosity, significant upgrades will be required for the LHC detectors. A key upgrade of the CMS detector is to incorporate the identification of charged particle trajectories in the hardware-based trigger system, with potential to not only solidify the CMS trigger strategy but to enable searches for completely new physics signatures. This seminar will discuss the motivation of the CMS track trigger, give an overview of the system, and discuss its expected performance based on simulation and hardware demonstration.
