Search for the standard model Higgs boson decaying to bottom quarks in
pp collisions at sqrt(s)=7 TeV
   [PDF]

CMS Collaboration
A search for the standard model Higgs boson (H) decaying to a b-quark pair
when produced in association with weak vector bosons (V) is reported for the
following modes: W(mu,nu)H, W(e,nu)H, Z(mu,mu)H, Z(e,e)H and Z(nu,nu)H. The
search is performed in a data sample corresponding to an integrated luminosity
of 4.7 inverse femtobarns, recorded by the CMS detector in proton-proton
collisions at the LHC with a center-of-mass energy of 7 TeV. No significant
excess of events above the expectation from background is observed. Upper
limits on the VH production cross section times the H to b-quark pair branching
ratio, with respect to the expectations for a standard model Higgs boson, are
derived for a Higgs boson in the mass range 110-135 GeV. In this range, the
observed 95% confidence level upper limits vary from 3.4 to 7.5 times the
standard model prediction; the corresponding expected limits vary from 2.7 to
6.7.
