The ATLAS discovery potential for MSSM neutral Higgs bosons decaying into muon, tau, supersymmetric particle pairs

The discovery potential for MSSM neutral Higgs bosons in the ATLAS experiment at centre-of-mass energy $\sqrt{s}$ = 14 TeV at the Large Hadron Collider (LHC) is discussed. The discovery and exclusion sensitivity in the (m$_A$, tan$\beta$) plane in different luminosity scenarios is discussed for three processes: h/A/H decaying into $\tau\tau$ or into $\mu\mu$ pairs or in supersymmetric particles (heavy neutralino/chargino pairs).
