---++ Abstract

<div style="max-width: 66em;">
Combined results are reported from searches for the standard model Higgs boson in proton-proton collisions at <nobr>&#8730;<i>s</i> = 7 !TeV</nobr> in five Higgs boson decay modes: &gamma;&gamma;, bb, &tau;&tau;, WW, and ZZ. The explored Higgs boson mass range is 110&ndash;600 !GeV. The analysed data correspond to an integrated luminosity of 4.6&ndash;4.8 fb<sup>&ndash;1</sup>. The expected excluded mass range in the absence of the standard model Higgs boson is 114.5&ndash;543 !GeV at 95% CL. The observed results exclude the standard model Higgs boson in the mass range 127.5&ndash;600 !GeV at 95% CL, and in the mass range 129&ndash;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 2.8 &sigma;, is observed for a Higgs boson mass hypothesis of 125 !GeV. The global significance of observing an excess with a local significance greater than 2.8 &sigma; anywhere in the search range 110&ndash;600 (110&ndash;145) !GeV is estimated to be 0.8 &sigma; (2.1 &sigma;). More data are required to ascertain the origin of this excess.  
For an extension of the standard model including a fourth generation of fermions (SM4), the SM4 Higgs boson is excluded in the mass range 120&ndash;600 !GeV at 95% CL.
In the fermiophobic Higgs boson scenario, a fermiophobic Higgs boson is excluded in the mass range 110&ndash;192 !GeV at 95% CL.
