High Energy Physics Seminars

The HL-LHC (high luminosity LHC) project offers new opportunities to fully explore the Higgs sector and to extend searches for new physics.  The experiments will need to be upgraded in order to survive the harsh experimental conditions.  The CMS experiment has an extensive program of upgrades including a SiPM-on-tile hadronic calorimeter in the endcap region.  Relative to designs targeted at a future e+e- collider, the CMS implementation of this technology has unique challenges related to the radiation field, event rate, and integration with the existing experiment.  We will review the status of the calorimeter project, now under construction, and highlight some lessons which may be relevant for future collider experiments.
