Title: Search for neutral MSSM Higgs bosons decaying to a pair of tau leptons in pp collisions

Abstract

Our search for neutral Higgs bosons in the minimal supersymmetric extension of the standard model (MSSM) decaying to tau-lepton pairs in pp collisions is performed, using events recorded by the CMS experiment at the LHC. The dataset corresponds to an integrated luminosity of 24.6 fb -1, with 4.9 fb -1 at 7 TeV and 19.7 fb -1 at 8 TeV. To enhance the sensitivity to neutral MSSM Higgs bosons, the search includes the case where the Higgs boson is produced in association with a b-quark jet. No excess is observed in the tau-lepton-pair invariant mass spectrum. Exclusion limits are presented in the MSSM parameter space for different benchmark scenarios, m h max , m h mod + , m h mod - , light-stop, light-stau, τ-phobic, and low- m H. Lastly, upper limits on the cross section times branching fraction for gluon fusion and b-quark associated Higgs boson production are also given.
