CP Violation and Strategies for Extracting CKM Phases

The phenomenon of CP violation and strategies for extracting the angles of the unitarity triangle are reviewed. Special emphasis is given to the B-meson system, as it plays an outstanding role to test the Standard Model description of CP violation at future experimental B-physics facilities. Both general aspects and recent developments are discussed. It is pointed out that combined branching ratios for Bu,d → πK modes, which have been observed recently by the CLEO collaboration, and untagged Bs → KK decays may allow us to derive interesting constraints on the CKM angle γ and may eventually lead to a solid determination of this angle.
