摘要：
We propose a new mechanism for late cosmological baryon asymmetry in models with first order electroweak phase transition. Lepton asymmetry arises through the decay of particles produced out of equilibrium in bubble collision and is converted into baryon asymmetry by sphalerons. Supersymmetric models with explicitly broken R-parity may provide a suitable framework for the implementation of this mechanism.
