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 signicant background rejection can be achieved using the presence of highly energetic charged leptons coming from the decays of W/Z. In the light mass 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 τ pair, both decaying hadronically. The analysis is based on data from proton-proton collisions collected with CMS detector in 2011 and 2012 corresponding to an integrated luminosity of 4.9 fb−1 at √s = 7TeV and 19.5 fb −1 at √s = 8TeV respectively. A data-driven technique, the fake rate method, has been used for background estimation. 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.
