摘要：

The mass spectrum and gauge-coupling renormalisation of a phenomenologically promising three-generation model is analysed in detail. Gauge-singlet superfields play an important role in overcoming a major problem which is generic to a large class of models. Throughout a large region of parameter space, a naturally light Higgs doublet is compatible with perturbative gauge couplings, unification and the experimental value of sin2θw. © 1990.
