Title: Physics of the High Luminosity LHC Upgrade

Speaker: Jay Hauser (UCLA)

Abstract: Following the discovery of the Higgs particle at CERN in 2012, a high luminosity upgrade program, HL-LHC, promises 6-10 times more proton-proton collisions than the current LHC accelerator by 2025.  With the increased number of collisions, as well as improvements to the main LHC detectors ATLAS and CMS, comes an improved physics measurement program.  For instance, it should be possible to make more precise measurements of the properties of Higgs and top quark particles, extend the reach of Supersymmetric particle searches, and improve searches in general for physics beyond the standard model. This talk addresses the question of whether the physics potential is worth the very large effort involved in the LHC accelerator and detector improvements.
