The Higgs boson, post-discovery: What we are learning about H(125) in Run 2 of the Large Hadron Collider

Since the discovery of the Higgs boson five years ago, the Compact Muon Solenoid collaboration has analyzed approximately five times more data, the majority of which was collected at the new, world-record collision energy of 13 TeV.  The diphoton and ZZ decay channels that lead to the discovery of the Higgs boson are now being used to make precise tests of the standard model, and Higgs couplings to third generation fermions are being established with new results from searches for decays to pairs of tau leptons and bottom quarks.  As a part of this, new analysis techniques have brought sensitivity to Higgs bosons produced via gluon fusion and decaying to pairs of bottom quarks, a channel historically considered unobservable at the Large Hadron Collider due to large backgrounds.  The program of studying Higgs boson decays expected in the standard model is augmented with targeted searches for beyond the standard model decays that are growing in statistical power.  In this talk, I will review these exciting developments in Higgs boson physics.
