Abstract
We perform a combination of searches for standard model Higgs boson production in collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of . The different production and decay channels have been analyzed separately, with integrated luminosities of up to and for Higgs boson masses . We combine these final states to achieve optimal sensitivity to the production of the Higgs boson. We also interpret the combination in terms of models with a fourth generation of fermions, and models with suppressed Higgs boson couplings to fermions. The result excludes a standard model Higgs boson at 95% C.L. in the ranges and , with an expected exclusion of . In the range , the data exhibit an excess over the expected background of up to 2 standard deviations, consistent with the presence of a standard model Higgs boson of mass 125 GeV.
