Abstract

We consider the production of charged Higgs scalar bosons at $e^{+}$ $e^{-}$ and hadron colliders as a probe of the ${WHZ}_{i}$ vertex which can be nonzero at the tree level in $E_{6}$ models. Substantial cross sections at both kinds of colliders are possible but backgrounds are very substantial. These backgrounds can, in principle, be dealt with. $e^{+}$ $e^{-}$ annihilation with a light $Z_{2}$ may offer the best hope of probing this new interaction.
