Event Details

Results of a search for a non-SM Higgs boson decaying to a pair of new light bosons, each of which consequently decays into boosted dimuon final state using the LHC data collected by the CMS experiment are presented. Such Higgs decays to new light bosons are predicted in a variety of models with additional “hidden” sectors weakly coupled to the SM particles. In this analysis we target only decays of a new light bosons to muon pairs that allows to test the light boson mass within range 0.25 - 3.55 GeV/c2. Results of the analysis are presented as a model-independent 95% CL upper limit on the product of the cross section times branching fraction times acceptance and are applicable to a broad class of non-SM scenarios. The results are also interpreted in two benchmark scenarios, Next-to-Minimal Supersymmetric SM (NMSSM) and the Supersymmetry with dark sector (dark SUSY).
