Study of associated $bbH, H \to \tau\tau$ channel: lepton-lepton and lepton-hadron final state

The analysis presented in this note is a comparative study of the observability potential in the lepton-lepton and lepton-hadron final state of a Higgs boson decay into tau lepton pair. Discussed are mass points mH=120GeV, 150GeV and 200GeV and production in b-quark fussion. It is based on fast simulation of the ATLAS detector. The cross-section enhancement of the MSSM regarding tan beta is not included. It is shown that introducing lepton-lepton mode to the analysis stream may increase significance about 20-40%.
