Abstract
This paper discusses the possibility to observe a signal from MSSM Higgs boson decays into final states containing four b-jets. Two specific channels are considered: bbH and bbA production with H,A -->bb, for large values of mH, mA and tan(beta), and H-->hh-->bbbb decays for 150 GeV < mH < 2 and for low values of tan(beta). Both channels are difficult to extract because of the very large reducible and irreducible QCD backgrounds. Even with an ultimate integrated luminosity, expected per LHC experiment, of 3*10**5 pb**-1, the region of the MSSM parameter space covered by these channels does not extend the reach beyond that accessible to other channels that were studied in the past. Nevertheless, their observation would help in constraining the couplings and branching ratios of the MSSM Higgs bosons.
