Recent Developments in Theory of CP Violation

Abstract

Four topics in theory of CP violation are reviewed. (a) CP violation in $B$ decays: We describe a new clean way of constraining the angle $\gamma$ of the unitarity triangle and how new CP violation in decay amplitudes can signal new physics. (b) CP violation in $K$ decays: We explain the special features of the decay $K_L\raπ^0ν\barν$ both as a measurement of Standard Model CP violating parameters and as a probe of new physics. (c) CP violation in $D$ decays: We describe the consequences of CP violation from new physics in $D-\bar{D}$ mixing. (d) CP violation in Supersymmetry: We explain how a combination of measurements of CP violating processes will give insight into the flavor and CP structure of supersymmetry.
