Description

Rare and exotic decays of the Higgs boson provide a unique
window for the discovery of new physics, as the Higgs boson may couple to leptons in flavour violating or otherwise anomalous ways, or to hidden-sector states that do not interact under the Standard Model gauge transformations. This talk summarizes recent ATLAS searches for unexpected decays of the 125 GeV Higgs boson: enhanced rates of dimuon decay, decay to two different charged leptons, and decay to new light bosons, H -> aa, where the a-bosons decay to various final states. These searches use LHC collision data at sqrt(s) = 13 TeV collected by the ATLAS experiment in Run 2.
