Search for a non-standard-model Higgs boson decaying to a pair of new light bosons in four-muon final states

Popis výsledku v původním jazyce

Results are reported from a search for non-standard-model Higgs boson decays to pairs of new light bosons, each of which decays into the mu(+)mu(-) final state. The new bosons may be produced either promptly or via a decay chain. The data set correspondsto an integrated luminosity of 5.3 fb(-1) of proton-proton collisions at root s = 7 TeV, recorded by the CMS experiment at the LHC in 2011. Such Higgs boson decays are predicted in several scenarios of new physics, including supersymmetric models with extended Higgs sectors or hidden valleys. Thus, the results of the search are relevant for establishing whether the new particle observed in Higgs boson searches at the LHC has the properties expected for a standard model Higgs boson. No excess of eventsis observed with respect to the yields expected from standard model processes. A model-independent upper limit of 0.86 +/- 0.06 fb on the product of the cross section times branching fraction times acceptance is obtained. The results, whi
