Search for Neutral Supersymmetric Higgs Bosons in b$\tau\tau$ Final States in $p\bar{p}$ Collisions at $\sqrt{s}$=1.96 TeV

We present a search for Higgs bosons produced via the associated $p\bar{p}\to h+b \to\tau+\tau+b$ process at a center-of-mass energy of $\sqrt{s}=$1.96~TeV using up to 4~fb$^{-1}$ of data collected with the D0 detector at the Fermilab Tevatron collider. In supersymmetric models Higgs boson production cross sections can be significantly enhanced compared to the Standard Model; additionally the Higgs boson has a significant branching ratio to tau leptons at all masses. This hybrid ``b-tau'' channel complements the di-tau search channel, in particular providing sensitivity around the $Z$ mass. Particular focus will be given to the case where one of the taus decays hadronically and the other to an electron.
