CP Violation: The Future of B Physics
  The subject of CP violation in B decays is reviewed in the Standard Model (SM) and beyond the SM. The present explanation of CP violation in terms of phases in the Cabibbo-Kobayashi-Maskawa (CKM) matrix can be tested through a variety of CP asymmtries in neutral and charged B decays. SM constraints on the CKM phases are violated by new mechanisms of CP nonconservation beyond CKM. Different mechanisms can be distinguished by combining measurements of CP asymmetries with rate measurements of so-called penguin B decays.
