description In the mhmax scenario of the Minimal Supersymmetric Extension of the Standard Model the b-quark associated Higgs production is among the most relevant channels. In this thesis an analysis of bbar h/A/H->tautau->leplep for the ATLAS detector at LHC with a center of mass energy of 14 TeV has been performed. The goal of this Monte Carlo study was to obtain the discovery potential for neutral, mass degenerated Higgs bosons with low and medium masses for different points in the mA - tanbeta plane. The results obtained by a cut-and-count analysis, using a fast simulation and without considering systematic uncertainties are the following: A Higgs boson with a mass of 120 GeV can be discovered if tanbeta is larger than 6. If the Higgs particle has a mass of 160 GeV it will be discovered if tanbeta is larger than 7. If its mass is about 200 GeV it can be discovered if a value of tanbeta larger than 10 is realized in nature.
