Spontaneous breaking of CP in SU(5), natural flavor conservation and the baryon asymmetry
Technical Report
·
OSTI ID:6056573
An SU(5) model is presented in which CP is spontaneously broken at the grand unification mass scale and that preserves all the features of the Weinberg model of CP-nonconservation with natural flavor conservation. Therefore, in 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 lliggs. The implications for CP-nonconserving effects in proton decay are also discussed.
