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.Invited talk at Flavor Physics and CP violation (FPCP), Philadelphia, May 2002High Energy Physics - PhenomenologyAstrophysicsGeneral Relativity and Quantum Cosmologytext
