Minimal supersymmetric standard model prediction for (WH -/+)-H-+/- production by gluon fusion at the CERN Large Hadron Collider - art. no. 095001

We discuss the associated W+/-H-/+ production in pp collision for the CERN Large Hadron Collider. A complete one-loop calculation of the loop-induced subprocess gg-->W+/-H-/+ is presented in the framework of the minimal super symmetric standard model (MSSM), and the possible enhancement of the hadron ic cross section is investigated under the constraint from the squark direc t-search results and the low-energy precision data. Because of the large de structive interplay in the quark-loop contributions between triangle-type a nd box-type diagrams, the squark-loop contributions turn out to be comparab le with the quark-loop ones. In particular, the hadronic cross section via gluon fusion can be extensively enhanced by squark-pair threshold effects i n the box-type diagrams, so that it can reach the size of the hadronic cros s section via the subprocess b (b) over bar-->W+/-H-/+ which appears at the tree level.
