Exotic Higgs decays at the LHC

Many interesting extensions to the Standard Model predict nonstandard decays of the 125 GeV Higgs boson. The ATLAS and CMS experiments at the LHC have searched for processes including decays of the Higgs boson to long-lived, weakly interacting particles, decays of the Higgs boson to dark photons, decays of the Higgs boson to pairs of new (pseudo)scalars, and lepton-flavor violating decays of the Higgs boson. This note will summarize the state of these analyses using data taken through the end of 2016.
