The most probable decay for a light Higgs Boson Standard Model (mH < 135 GeV) is H → b¯b; the signal competes with background mostly due to multijet processes (QCD). The poster summarizes the analysis status with data sample corresponding to an integrated luminosity of about 4.7 fb
−1, collected in 2011 by the Compact Muon Solenoid experiment during the Large Hadron Collider proton-proton collisions at a centre of mass energy √s = 7TeV. The Standard Model Higgs H, produced in association with a vector boson V , is studied in five different final states, where H → b¯b and the vector boson decays to charged leptons
(e, μ) and neutrinos. The poster shows the resulting global limit on production cross section of Higgs boson and weak bosons, pp → VH + X. The poster also includes information on recent light Higgs boson searches studying the H → ττ decay. Such a final state is also important in the context of MSSM neutral Higgs boson searches
