Supersymmetric-QCD corrections to W±H± associated production at the CERN Large Hadron Collider

We calculate the SUSY-QCD corrections to the inclusive total cross sections of the associated production processes pp→W±H±+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 tanβ (∼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 pT and rapidity Y of W-boson, and the invariant mass MW+H-
