The dominant production mechanism for Standard Model (SM) Higgs boson is gg->h. However, in certain beyond the SM scenarios, Higgs production with bottom quarks can become dominant due to enhanced bottom quark Yukawa coupling. One such model is the Minimal Supersymmetric Standard Model (MSSM) where the bottom Yukawa coupling to Higgs bosons, including the SM-like Higgs, gets significantly modified for large values of tan(beta) [defined as the ratio of the vacuum expectation values of the up and down type Higgs]. In this talk, I focus on one-loop supersymmetric QCD corrections to the subprocess b g->b h which is the leading order (LO) process in five flavor number PDF scheme (5FNS) when one bottom quark in the final state is tagged. In particular, I investigate the validity of the commonly used Delta_b approximation where one rescales the bottom Yukawa in MSSM in order to include large tan(beta) effects.
