The CMS Trigger: Through the Ages
A trigger represents a fundamental component of hadron collider experiments. The ability to separate signal from background on extremely short time-scales represents a major technological and intellectual challenge. This seminar will seek to explain how the trigger system for the CMS Experiment at the LHC has evolved from the first run (2010 - 2012) through to its first major upgrade in 2016, where a significantly more advanced trigger was deployed. The focus will be on discussing custom electronics, architecture choices, and ultimate performance. With preparations well underway for High Luminosity LHC, the challenges and status of the next major overhaul of the trigger system will be also be described.

HL-LHC and HE-LHC physics prospects
The Large Hadron Collider (LHC) has been successfully delivering proton-proton collision data at a centre of mass energy of 13 TeV. An upgrade is planned to increase the instantaneous luminosity delivered by the LHC by a factor of 5-7 (HL-LHC) for running in 2026 and beyond and there is also another possible future upgrade considered for running at an energy of 27 TeV at the high-energy LHC (HE-LHC). In the last 1.5 years, the LHC experiments prepared a CERN Yellow Report which summarises the physics reach for HL-LHC and HE-LHC and serves as input to the European Strategy this year. This talk shows highlights of the physics reach at the HL-LHC and HE-LHC detailed in the report. The physics prospects are shown for Higgs couplings measurements, di-Higgs boson production sensitivity, Vector Boson Scattering prospects as well as the discovery potential for electroweak SUSY and other exotic benchmark scenarios.
