Combined Search for the Standard Model Higgs Boson Decaying to bb¯ Using the D0 Run II Data Set
Abstract
We present the results of the combination of searches for the standard model Higgs boson produced in association with a W or Z boson and decaying into bb¯ using the data sample collected with the D0 detector in pp¯ collisions at s=1.96TeV at the Fermilab Tevatron Collider. We derive 95% C.L. upper limits on the Higgs boson cross section relative to the standard model prediction in the mass range 100GeV≤MH≤150GeV, and we exclude Higgs bosons with masses smaller than 102 GeV at the 95% C.L. In the mass range 120GeV≤MH≤145GeV, the data exhibit an excess above the background prediction with a global significance of 1.5 standard deviations, consistent with the expectation in the presence of a standard model Higgs boson.
