Abstract
A search is presented for decays beyond the standard model of the 125GeV Higgs bosons to a pair of light bosons, based on models withextended scalar sectors. Light boson masses between 5 and 62.5 GeV areprobed in final states containing four tau leptons, two muons and two bquarks, or two muons and two tau leptons. The results are from data inproton-proton collisions corresponding to an integrated luminosity of19.7 fb(-1), accumulated by the CMS experiment at the LHC at acenter-of-mass energy of 8TeV. No evidence for such exotic decays isfound in the data. Upper limits are set on the product of the crosssection and branching fraction for several signal processes. The resultsare also compared to predictions of two-Higgs-doublet models, includingthose with an additional scalar singlet.File | Dimensione | Formato | |
