Abstract

We calculate the SUSY-QCD corrections to the inclusive total cross sections of the associated production processes $p p \to W^{\pm} H^{\mp} + X$ in the Minimal Supersymmetric Standard Model(MSSM) at the CERN Large Hadron Collider(LHC). The SUSY-QCD corrections can increase and decrease the total cross sections depending on the choice of the SUSY parameters. When $μ < 0$ the SUSY-QCD corrections increase the leading-order (LO) total cross sections significantly for large tan $β$ ( $\sim 40$ ), which can exceed $10 %$ and have the opposite sign with respect to the QCD and the SUSY-EW corrections, and thus cancel with them to some extent. Moreover, we also investigate the effects of the SUSY-QCD on the differential distribution of cross sections in transverse momentum $p_{T}$ and rapidity Y of W-boson, and the invariant mass $M_{W^{+} H^{-}}$ .
