Abstract

Searches for the standard model Higgs boson decaying into b quarks and produced in association with either vector bosons or top quark pairs are performed in proton-proton collisions with the CMS detector at the LHC. A search for neutral Higgs bosons decaying into b quarks and produced in association with at least one additional b quark is also performed. This mode is expected to be particularly sensitive to Higgs bosons in MSSM scenarios with large values of the parameter tan . -1 -0.9 -0.8 -0.7 -0.6 -0.5 -0.4 -0.3 -0.2 -0.1 Entries / 0.06 -1 -0.9 -0.8 -0.7 -0.6 -0.5 -0.4 -0.3 -0.2 -0.1 Data/MC 0.5 1 1.5 2 MC uncert.

Introduction

In this paper we present searches for the SM Higgs boson decaying into a b-quark pair in the production modes pp → VH, where V is either a Z or a W boson decaying leptonically, and pp → ttH, where top quarks decay into either lepton plus jets or dileptons. We present a searches for MSSM neutral Higgs bosons produced in association with at least one b quark, and decaying into a pair of b quarks, pp → bφ+X, φ → bb
