Abstract

Inspired by the recent LHC Higgs data and null search results of supersymmetry (SUSY), we scan the parameter space of the Minimal Supersymmetric Standard Model (MSSM) with relatively heavy sparticles (1-3 TeV). Then in the parameter space allowed by current collider experiments and dark matter detections, we calculate the complete one-loop SUSY QCD corrections to ppbbˉhpp\to b\bar{b}h at the LHC with s=14\sqrt{s}=14 TeV and obtain the following observations: (i) For the large values of tanβ\tan\beta and low values of mAm_{A}, the SUSY QCD effects can be quite large, which, however, have been excluded by the latest results of LHC search for H/Aτ+τH/A \to \tau^{+}\tau^{-}; (ii) For modest values of tanβ\tan\beta and mAm_{A} which so far survived all experimental constraints, the SUSY QCD corrections can maximally reach about -9%.
