The authors examine the production of light Higgs bosons associated with electroweak symmetry-breaking in an E/sub 6/ superstring model in Z {omega} HZ/sup */ decays, in e/sup +/e/sup -/ annihilation and in toponium decays. They find that the couplings of the lightest scalar Higgs boson H/sub 1//sup 0/ in these models are very similar to those of the standard Higgs boson unless the pseudoscalar P/sup 0/ in the model has mass {le} M/sub z/. Possible new modes for Higgs boson production not found in the standard model are presented. The authors give simple analytic expressions for the Higgs boson masses and mixing angles in the limit that the extra Z' gauge boson is heavy which clearly shows the production mechanisms that are favored for a given set of model parameters.
