Description
Several models of new physics predict the existence of new light bosons that are weakly coupled to SM particles. Two examples include SUSY with a "dark" sector (in which the new light bosons can also be relatively long-lived) or models with an extended Higgs sector, e.g. NMSSM. In these scenarios, the new bosons can be produced either in the Higgs decays or as part of SUSY cascades. Non-SM decays of the Higgs can either hide the Higgs boson from standard searches or slightly alter the measured cross-section of the SM Higgs boson candidate observed at the LHC. Direct searches for non-SM decays of the Higgs boson provide a complementary approach to SM Higgs searches and can help further understand the nature of Higgs boson by either confirming or rejecting large classes of BSM scenarios. We present the status and recent 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.
