Nieves, J F

We present an SU(5) model in which CP is spontaneously broken at the grand unification mass scale and which preserves all the features of the Weinberg model of CP nonconservation with natural flavor conservation. Therefore, a contrast to a model recently proposed by Branco, in the present model a net cosmological baryon asymmetry can be generated through the decays of superheavy Higgs bosons. The implications for CP-nonconserving effects in proton decay are also discussed.
