Search for Neutral Supersymmetric Higgs Bosons in b$\tau\tau$ Final States

We report preliminary results in a search for neutral Higgs bosons via the channel $p\bar{p}\to h+b \to\tau+\tau+b$ using 2 fb$^{-1}$ of data collected by the D0 experiment at the Tevatron. One tau is required to decay to a muon and a pair of neutrinos, and the other one to decay hadronically. The result is interpreted in terms of upper limits on the Higgs boson production cross section in supersymmetric models.
