Search for neutral Higgs bosons in the multi-b -jet topology in 5.2 fb−15.2 fb−1 of pp¯ collisions at at √s=1.96 TeV

Abstract

Data recorded by the D0 experiment at the Fermilab Tevatron Collider are analyzed to search for neutral Higgs bosons produced in association with b quarks. The search is performed in the three-b -quark channel using multijet-triggered events corresponding to an integrated luminosity of 5.2 fb−15.2 fb−1. In the absence of any significant excess above background, limits are set on the cross section multiplied by the branching ratio in the Higgs boson mass range 90 to 300 GeV, extending the excluded regions in the parameter space of the minimal supersymmetric standard model.
