Search for light bosons in decays of the 125 GeV higgs boson in proton-proton collisions at √s=8 TeV

A search is presented for decays beyond the standard model of the 125 GeV Higgs bosons to a pair of light bosons, based on models with extended scalar sectors. Light boson masses between 5 and 62.5 GeV are probed in final states containing four τ leptons, two muons and two b quarks, or two muons...
