Search for MSSM heavy neutral Higgs bosons in the four-b final state

A study on the observability potential of the two heaviest Minimal Supersymmetric neutral Higgs bosons in the 4 b-jet channel with the CMS detector at LHC is presented, focusing the attention on the medium term stage of data taking (at $2x10^{33}cm^{-2}s^{-1}$) when a high luminosity has been accumulated. Prospects for exclusion regions of the (\mA,\tanb) plane are presented. Possible trigger options for this channel based on current CMS HLT table are studied. Background estimation plans from future LHC data are also proposed.
