Supersymmetric Higgs Bosons Discovery Potential at Hadron Colliders through $bg$ channel

We explore the discovery potential of the supersymmetric Higgs bosons through $bg$ channel at Tevatron and LHC. Compared with the process of $qq' \to WH$, this channel is more advantigeous to finding the supersymmetric Higgs bosons at Tevatron if $\tan\beta$ is larger than ten.
