Exotic Higgs Decays

Exotic decays of the Standard Model-like Higgs boson into beyond-the-Standard Model particles are predicted in a wide range well-motivated theories. The enormous samples bosons that have been and will be produced at Large Hadron Collider thus constitute one key discovery opportunities facility, particularly upcoming high-statistics high-luminosity run. Here we review recent theoretical work on models predict or accommodate exotic decays, status current experimental searches, look forward to future capabilities dedicated factories beyond.
