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

Abstract

Production of charged Higgs boson associated with a W gauge boson at the LHC is mainly induced by the tree-level [Formula: see text] 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 σ of the process pp→H±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 σ is smaller than that predicted by the LRTH model or SUSY. The value of σ within the LRTH model is larger or smaller than the SUSY case, which depends on the relevant free parameters.
