Description
A search for the Standard Model (SM) Higgs boson decaying to bottom quarks
pairs is presented. Two production channels have been analyzed: vector-boson
fusion and associated production with a vector boson decaying to leptons. The
search is performed on data collected with the CMS detector at LHC during 2011
and 2012, at center-of-mass energies of 7 and 8 TeV, corresponding to integrated
luminosities of about 5.0 fb-1 and 19.0 fb-1, respectively. A 95% confidence
level upper limit of 1.79 (0.89) times SM Higgs boson cross section has been
observed (expected) at a Higgs boson mass of 125 GeV. An excess of events is
observed above the expected background with a local significance of 2.2 standard
deviations, which is consistent with the expectation from the production of the
SM Higgs boson. The signal strength corresponding to this excess, relative to
that of the SM Higgs boson, is 0.97+-0.48.
