Abstract

We propose a mechanism for generating the baryon asymmetry of the Universe in the framework of spontaneously broken gauge theories with CP-nonconversation and baryon number violation. An SU(2) ⊗ U(1) model is worked out in detail, in which it proves to be possible to construct universal superweak baryon and CP-nonconserving interaction mediated by new scalar boson with mass not exceeding that of W-boson.
