摘要：

We examine the constraints on baryogenesis if anomalous weak baryon violation is in thermal equilibrium at high temperatures. If neutrinos have Majorana masses, there is an upper bound on the scale of baryogenesis: T0≲1012 GeV(1 eV/mν)2, where mν is the mass of the lightest neutrino, and no baryon number is generated at temperatures below T0. © 1990.
