SUSY-QCD Corrections to $W^{pm}H^{mp}$ Associated Production at the CERN Large Hadron Collider


Abstract in English

We calculate the SUSY-QCD corrections to the inclusive total cross sections of the associated production processes $ppto W^{pm}H^{mp}+X$ 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 $mu<0$ the SUSY-QCD corrections increase the leading-order (LO) total cross sections significantly for large tan$beta$ ($sim 40$), 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 $M_{W^+H^-}$.
