The discovery of the Higgs boson, and precision measurements at the energy frontier as a path to physics beyond the Standard Model

Abstract: The observation of a new particle with properties consistent with a Standard Model Higgs boson by the ATLAS and CMS collaborations in 2012 marked a major achievement in particle physics, fulfilling a primary goal of the LHC program.  Continuing measurements of the properties of the new boson constitute stringent tests of the Standard Model in previously unexplored phase space.  Aside from direct searches for new particles, ongoing measurements of the full range of Standard Model processes at the LHC over a wide range of phase space and with increasing precision represent an essential path to the discovery of physics beyond the Standard Model.  Results and historical perspective will be presented for the search, discovery and measurements of the
Higgs boson, with a particular focus on the di-photon final state in CMS.  Prospects for the use of further measurements of the Higgs and electroweak gauge bosons to expose physics beyond the Standard Model will be discussed, as well as the role and use of machine learning in reconstruction, simulation and physics analysis.  Physics prospects and detector requirements through the HL-LHC era and beyond will be explored, with a particular focus on the use of precision timing to suppress pileup and extend physics capabilities.
