Title: Discovery potential for the MSSM H/A bosons decaying to two muons at ATLAS

Abstract

The ATLAS sensitivity for the H/A{yields} {mu}{mu} decay (mA =300 GeV/c2 and tan{beta} =30) for the initial detector setup has been estimated using the full simulation. The selection criteria have been optimized for both the direct and the associated production (bbH/A) of the Higgs bosons. The irreducible Drell-Yan background dominates in the direct production case and overwhelms the signal in such a way that the direct production has lower signal significance. In the associated production case, the Zb b-bar background is the irreducible one, but the most abundant is the tt-bar background and the selection criteria applied were optimized for its reduction. The signal significance was calculated for both analyses separately and for their combination.
