Detection of Neutral MSSM Higgs Bosons in Four-$b$ Final States at the Tevatron and the LHC: An Update

We update our earlier results regarding detection of $gg\to b\anti b h\to 4b$ ($h=h^0,H^0,A^0$) to incorporate the very high $b$-tagging efficiencies and purities that are now anticipated at the LHC. New results for the Tev$^*$ are given, and indicate substantial potential for these modes. The complementarity of the $H^0\to h^0h^0 \to 4b$ final state mode is illustrated for the LHC. The latest radiative corrections to the Higgs sector are incorporated.
