  Combined results are reported from searches for the standard model Higgs
boson in proton-proton collisions at sqrt(s)=7 TeV in five Higgs boson decay
modes: gamma pair, b-quark pair, tau lepton pair, W pair, and Z pair. The
explored Higgs boson mass range is 110-600 GeV. The analysed data correspond to
an integrated luminosity of 4.6-4.8 inverse femtobarns. The expected excluded
mass range in the absence of the standard model Higgs boson is 118-543 GeV at
95% CL. The observed results exclude the standard model Higgs boson in the mass
range 127-600 GeV at 95% CL, and in the mass range 129-525 GeV at 99% CL. An
excess of events above the expected standard model background is observed at
the low end of the explored mass range making the observed limits weaker than
expected in the absence of a signal. The largest excess, with a local
significance of 3.1 sigma, is observed for a Higgs boson mass hypothesis of 124
GeV. The global significance of observing an excess with a local significance
greater than 3.1 sigma anywhere in the search range 110-600 (110-145) GeV is
estimated to be 1.5 sigma (2.1 sigma). More data are required to ascertain the
origin of this excess.
