LHC Detection of Neutral MSSM Higgs Bosons via $gg\rta b\anti b \h\rta b\anti b b\anti b$

Abstract

We demonstrate that simultaneous detection of two of the neutral Higgs bosons of the Minimal Supersymmetric Model will be possible at the LHC in the $b\anti b b\anti b$ final state, provided $\tanb$ is large and $b$-tagging can be performed with good efficiency and purity. This mode enhances the already established guarantee that there is no region of supersymmetric parameter space for which {\it none} of the Higgs bosons of the model can be seen at the LHC.
