Possible appearance of the baryon asymmetry of the universe in an electroweak theory
A new mechanism is proposed for the generation of the baryon asymmetry of the universe in an electroweak theory. This mechanism involves an anomalous nonconservation of baryon number at high temperatures. A cosmological limitation on the mass of a Higgs boson is derived: 10 GeV S mH S 60 GeV. The sign of the baryon asymmetry is determined by the sign of the CP breaking in the decays of A'0 mesons.
