Study of gg rightarrow b bar{b}H_{SUSY},H_{SUSY} ightarrow tau tau rightarrow ll+X

The neutral MSSM Higgs bosons are studied with fast simulations in the tau tau decay channel with fully leptonic final states. The results are updated for three years of LHC operation at low luminosity. The effect of high luminosity conditions and pile-up events is studied and preliminary results are given. The reach of the lepton lepton final state in the MSSM parameter space is discussed and compared with the corresponding MSSM Higgs to tau tau to electron muon (+X) channel.
