PRODUCTION OF CHARGED HIGGS BOSON ASSOCIATED WITH A W GAUGE BOSON AT THE LHC

Production of charged Higgs boson associated with a W gauge boson at the LHC is mainly induced by the tree-level b (b) over bar annihilation and the one-loop gg fusion. In the context of the Higgs triplet model (HTM) and the left right twin Higgs (LRTH) model, we calculate the production cross-section sigma of the process pp -> (HW -/+)-W-+/- and compare our results with those given by supersymmetry (SUSY). We find that in most of the parameter space of the HTM, the production cross-section sigma is smaller than that predicted by the LRTH model or SUSY. The value of sigma within the LRTH model is larger or smaller than the SUSY case, which depends on the relevant free parameters.
