Abstract

The production cross sections for the process {ital e}{sup +}{ital e{minus}}{r arrow}{ital H}{sub {ital i}}{sup 0}{ital H+}{ital H{minus}} are calculated in the two-Higgs-doublet model. We consider the situations in which {ital H}{sub {ital i}}{sup 0} could be produced either from the propagator exchange or from the initial legs or the final legs. At {radical}{ital s} =300 GeV, this process can be detected if the mass of the Higgs boson {ital H}{sub {ital i}}{sup 0} is smaller than {ital M}{sub {ital Z}}. Our calculations show that the situation in which the propagator exchange is {ital ZZ} becomes the dominant one, while the other situations are negligible.
