We investigate the prospects for the discovery of a neutral Higgs boson produced in association with a b quark, followed by the Higgs decay into a pair of bottom quarks, pp\ensuremath→b\ensuremathφ0\ensuremath→bbb+X, at the CERN Large Hadron Collider (LHC) within the framework of unified supersymmetric models. The Higgs boson \ensuremathφ0 can be a heavy scalar H0 or a pseudoscalar A0. Furthermore, this direct discovery channel is compared with the indirect Higgs searches in the rare decay Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath- at hadron colliders. Promising results are found for the minimal supergravity model, the anomaly-mediated supersymmetry breaking model, and the gauge-mediated supersymmetry breaking model. We find that the indirect search for B(Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath-)\ensuremath≥5\ifmmode×\else\texttimes\fi10^\ensuremath-9 is complementary to the direct search for b\ensuremathφ0\ensuremath→bbb with √(s)=14 TeV and an integrated luminosity (L) of 300 fb^\ensuremath-1. In the anomaly-mediated supersymmetry breaking and gauge-mediated supersymmetry breaking models, b\ensuremathφ0\ensuremath→bbb with L=300 fb^\ensuremath-1 covers a larger area in the parameter space than B(Bs\ensuremath→\ensuremathμ+\ensuremathμ^\ensuremath-)\ensuremath≥5\ifmmode×\else\texttimes\fi10^\ensuremath-9. In addition, we present constraints from b\ensuremath→s\ensuremathγ and muon anomalous dipole moment (\ensuremathΔa_\ensuremathμ) on the parameter space.
