Abstract
We report results from a search for production of a neutral Higgs boson in association with a b quark. We search for Higgs decays to tau pairs with one tau subsequently decaying to a muon and the other to hadrons. The data correspond to 2.7 fb(-1) of pp collisions recorded by the D0 detector at square root(s)=1.96 TeV. The data are found to be consistent with background predictions. The result allows us to exclude a significant region of parameter space of the minimal supersymmetric model.
Highlights
This search requires reconstruction of muons, hadronic decays, jets (arising from b quarks), and neutrinos

The current model of physics at high energies, the standard model (SM), has withstood increasingly precise experimental tests, the Higgs boson needed to mediate the breaking of electroweak symmetry [1] has not been found
Summary
This search requires reconstruction of muons, hadronic decays, jets (arising from b quarks), and neutrinos. The yields for signal and each background are calculated as the product of the acceptance times efficiency determined from simulation, luminosity, and predicted cross sections.
