Abstract

The dominant contributions to W{sup {+-}H{+-}} production at the LHC are the tree-level bb annihilation and the gg fusion. We perform for the case of the complex minimal supersymmetric standard model (MSSM) a complete calculation of the next-to-leading order (NLO) electroweak corrections to the bb annihilation channel and a consistent combination with other contributions including the standard and supersymmetric-QCD (SUSY-QCD) corrections and the gg fusion, with resummation of the leading radiative corrections to the bottom-Higgs couplings and the neutral Higgs boson propagators. We observe a large CP-violating asymmetry, arising mainly from the gg channel.
