Abstract: (APS)

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 nBnγ≈10−8 is obtained in models where superheavy Higgs mesons decay with complex amplitude into other Higgs mesons. By contrast, in the Kobayashi-Maskawa model nBnγ≈O(10−20).
