摘要：

We have examined the magnitude of the cosmological baryon asymmetry arising in several of the standard models of CP violation. Agreement with the experimental baryon to photon number ratio nBn10-8 is obtained in models where superheavy Higgs mesons decay with complex amplitude into other Higgs mesons. By contrast, in the Kobayashi-Maskawa model nBnO(10-20). © 1979 The American Physical Society.
