CHARGED HIGGS BOSON PRODUCTION IN E-E- COLLISIONS

We consider the production of two single charged Higgs bosons at TeV e-e- colliders within the framework of the two-Higgs-doublet extension to the standard model. If the relations among the masses and couplings found in the SUSY version of this model hold, we find cross-sections which are very sensitive to tan β=ν2/ν1, and are highly suppressed by cancellations among the various contributions. In more general two-doublet models, the cancellations were found to be less important and generally larger cross-sections were obtained. Although the expected event rate for this process is small it provides a way to probe the details of the Higgs physics of the two-doublet model and the higher luminosities of e-e- machines may allow this reaction to be seen at statistically significant rates. © 1990.
