Study of H -> Tau Tau with Hadronic Tau Decays in CMS

A detailed study for H ra tau tau with fully hadronic final states in MSSM is presented with full simulation of the hadronic Tau Trigger, identification of tau ra hadrons + nu in the tracker, tau tagging with impact parameter measurement, E_T miss measurement and Higgs boson mass reconstruction. The discovery range in the m_A, tan beta parameter space is evaluated with parametrized impact parameter uncertainties from full simulation for b tagging.
