Search for neutral MSSM Higgs bosons decaying to μ+μ− in pp collisions at $\sqrt{s}$ = 7 and 8 TeV


CMS Collaboration; Canelli, F; Chiochia, V; Kilminster, B; Robmann, P; et al (2016). Search for neutral MSSM Higgs bosons decaying to μ+μ− in pp collisions at $\sqrt{s}$ = 7 and 8 TeV. Physics Letters B, 752:221-246.

Abstract

A search for neutral Higgs bosons predicted in the minimal supersymmetric standard model (MSSM) for$μ^{+}μ^{−}$ decay channels is presented. The analysis uses data collected by the CMS experiment at the LHC in proton–proton collisions at centre-of-mass energies of 7 and 8 TeV, corresponding to integrated luminosities of 5.1 and 19.3 fb$^{−1}$ , respectively. The search is sensitive to Higgs bosons produced either through the gluon fusion process or in association with a bb‾ quark pair. No statistically significant excess is observed in the $μ^{+}μ^{−}$ mass spectrum. Results are interpreted in the framework of several benchmark scenarios, and the data are used to set an upper limit on the MSSM parameter tan⁡β as a function of the mass of the pseudoscalar A boson in the range from 115 to 300 GeV. Model independent upper limits are given for the product of the cross section and branching fraction for gluon fusion and b quark associated production at $\sqrt{s}$=8 TeV . They are the most stringent limits obtained to date in this channel.
