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.Comment: 8 pages, 5 figures, Contribution to SUSY 02, Hamburg, Germany, June
