Abstract:
Mediation of flavor and CP violation through the Kobayashi-Maskawa quark mixing matrix is a genuine and well-established mechanism of the Standard Model of Elementary Particle Physics. The success of this simple description currently suggests that "minimal flavor violation", i.e. the Standard Model variant to break the flavor and CP symmetry, could hold approximately at energies as high as a TeV, where we expect to see new particles beyond the Standard Model, for instance, directly at the Large Hadron Collider. One of the important questions in flavor physics is whether this organizing principle passes all benchmark tests, irrespective of a potential future breakdown of the Standard Model related to its Higgs sector.
We present the status of flavor and CP violation within the Standard Model in view of the current experimental and theoretical situation, and discuss the implications for New Physics models including Supersymmetry. We highlight future opportunities to search for New Physics with flavor and CP breaking observables (flavor-changing neutral current processes, EDMs), with minimal flavor and CP, or beyond. If it turns out that the New Physics is not minimal in flavor symmetry breaking, it is connected to the origin of flavor.
