Abstract

The Standard Model (SM) Higgs boson is mainly produced from gluon-gluon and vector boson fusion at LHC. The associated production with vector bosons, although with a lower cross section, can be also considered a sensitive channel because a significant background rejection can be achieved using the presence of highly energetic charged leptons coming from the decays of W/Z. In the lightmass region, the SM Higgs boson decay into τ -lepton pairs has the second highest branching ratio, after the decay into b¯ b. For these reasons, a search for WH process is performed, in which the W boson decays into muon or electron, and the Higgs boson into a τ -pair, in which one τ decays into leptons and the other hadronically (τh). The analysis is based on data collected with the CMS detector during 2011, corresponding to an integrated luminosity of 4.7 fb−1 at a center-of-mass energy of 7TeV at LHC. The results are consistent with the expected SM background, so upper limits are set at 95% CL for the SM Higgs boson production cross section. The method used to estimate the background from data, is based on the fake-rate technique (CMS Physics Analysis Summary, CMS PAS HIG-12-006 (2012)).
