Combined search for the Higgs boson with the D0 experiment

We perform a combination of searches for standard model Higgs boson production in pp¯ collisions recorded by the D0 detector at the Fermilab Tevatron Collider at a center of mass energy of s√=1.96  TeV. The different production and decay channels have been analyzed separately, with integrated luminosities of up to 9.7  fb−1 and for Higgs boson masses 90≤MH≤200  GeV. 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 90
