Associated W+/- H-/+ production at e+ e- and hadron colliders

We show some results in the minimal supersymmetric Standard Model (MSSM) and the two Higgs doublet model (THDM) for W+/- H-/+ production cross sections at e+ e- and hadron colliders. We demonstrate that the predictions for the cross sections in the two models can be vastly different. Observing these processes, once the existence of a charged Higgs is established, might shed some light on the underlying model for an extended Higgs sector.
