Tomo Lazovich (Harvard) "One Higgs, Two Higgs, Old Higgs, New Higgs: the Higgs boson from discovery to new physics with the ATLAS experiment"

The discovery of the Higgs in Run 1 of the LHC provided a more complete picture of the Standard Model and also gave particle physicists a new tool to use in the search for Beyond the Standard Model physics. With center of mass energy now at 13 TeV in LHC Run 2, we are poised to produce new resonances and probe higher energy scales. I will first discuss the challenging WW decay channel of the Higgs and how we went from discovery to the current best measurement of the Higgs cross section and observation of the vector boson fusion production mode. I will then discuss searches for new physics in both resonant and non-resonant production of two Higgs bosons in the 4b final state in Run 2, detailing the advantages and difficulties of using this final state to search for new physics over a wide range of masses.
