Superstrings compactified on Calabi-Yau manifolds can yield additional light gauginos, Higgs fermions and bosons beyond those in the supersymmetic standard model. We explore the phenomenological constraints on minimal model parameters imposed by the experimental non-observation of charginos and charged Higgs bosons, as well as by cosmological constraints on neutralinos. We find that one or more charged fermions, charged bosons, and neutral bosons could be light enough to be produced at LEP.

Abstract
Superstrings compactified on Calabi-Yau manifolds can yield additional light gauginos, Higgs fermions and bosons beyond those in the supersymmetic standard model. We explore the phenomenological constraints on minimal model parameters imposed by the experimental non-observation of charginos and charged Higgs bosons, as well as by cosmological constraints on neutralinos. We find that one or more charged fermions, charged bosons, and neutral bosons could be light enough to be produced at LEP. The couplings and production mechanisms for these particles are discussed. © 1987.File in questo prodotto:
