Discovery potential of MSSM Higgs bosons with ATLAS

Abstract

In this article the potential of the ATLAS experiment to discover MSSM Higgs bosons is discussed. Various Monte-Carlo studies for SM Higgs boson production and dedicated MSSM Higgs boson analyses are taken into account to investigate the discovery potential in four different CP-conserving MSSM benchmark scenarios, the Mh–max scenario, the no mixing scenario, the gluophobic scenario and the small α scenario. The most recent theoretical calculations are used for the prediction of Higgs masses and couplings. The results are shown for integrated luminosities of 30 and 300 inverse fb. With 300 inverse fb, a five sigma discovery of at least one Higgs boson state is possible in all scenarios for all values of tanβ and MA. The heavy neutral and charged Higgs states can only be discovered in parts of the parameter space.
