Minimal supersymmetric standard model prediction for W^{+/}H^{/+} production by gluon fusion at the CERN Large Hadron Collider
Abstract
We discuss the associated W^{+/}H^{/+} production in pp collision for the CERN Large Hadron Collider. A complete oneloop calculation of the loopinduced subprocess gg>W^{+/}H^{/+} is presented in the framework of the minimal supersymmetric standard model (MSSM), and the possible enhancement of the hadronic cross section is investigated under the constraint from the squark directsearch results and the lowenergy precision data. Because of the large destructive interplay in the quarkloop contributions between triangletype and boxtype diagrams, the squarkloop contributions turn out to be comparable with the quarkloop ones. In particular, the hadronic cross section via gluon fusion can be extensively enhanced by squarkpair threshold effects in the boxtype diagrams, so that it can reach the size of the hadronic cross section via the subprocess bb¯>W^{+/}H^{/+} which appears at the tree level.
