The Large Hadron Collider (LHC) is the world’s most energetic particle accelerator complex, colliding protons at close to the speed of light. The LHC provides an extremely powerful tool to address fundamental questions about our Universe, including the nature of dark matter, the observed matter-antimatter asymmetry, and the origin of the large difference between the electroweak and Planck energy scales.
The LHC is scheduled to be upgraded to its high luminosity counterpart (HL-LHC) in about five years. The HL-LHC will significantly increase the intensity of the proton collisions, in turn enabling the LHC experiments to collect immense data sets to measure properties of the Higgs boson is great detail, probe very rare Standard Model processes, and search for signs of new physics beyond the well-established Standard Model. The increase in intensity, although scientically exciting, comes at the price of extremely challenging experimental data-taking conditions. These are particularly challenging for the real-time data filtering ('trigger') systems that are responsible for deciding which collision events to read out and store for later analysis.
In this colloquium, I will discuss the movitation and physics potential of the high luminosity LHC upgrade, as well as some of the associated experimental challenges, in particular in the context of the CMS experiment's trigger system.
