Higgs-boson production associated with a single bottom quark in supersymmetric QCD

Due to the enhancement of the couplings between Higgs bosons and bottom quarks in the minimal supersymmetric standard model (MSSM), the cross section of the process $pp\left(p\overline{p}\right)\to h^0{b(h}^0\overline{b})+X$ at hadron colliders can be considerably enhanced. We investigate the production of a Higgs boson associated with a single high-$p_T$ bottom quark via the subprocess $bg\left(\overline{b}g\right)\to h^0{b(h}^0\overline{b})$ at hadron colliders including the next-to-leading-order (NLO) QCD corrections in the MSSM. We find that the NLO-QCD correction in the MSSM reaches $50\%–70\%$ at the CERN LHC and $60\%–85\%$ at the Fermilab Tevatron in our chosen parameter space.
