We propose a scenario that generates the observed baryon asymmetry of the Universe through a multi--step phase transition in which SU(3) color symmetry is first broken and then restored. Two mechanisms produce a baryon asymmetry: one is analogous to conventional electroweak baryogenesis; the second involves spontaneous violation of $B-L$ conservation near the phase boundary. The contribution from the electroweak mechanism dominates, while the spontaneous violation of $B-L$ conservation leaves a… Expand
