CP violation and cosmology

Abstract

Microscopic CP violation has profound cosmological consequences. In particular, it is related to the baryon asymmetry of the universe. A successful baryogenesis requires new sources of CP violation in addition to the Cabibbo-Kobayashi-Maskawa phase. I give a brief review of the possibilities.
