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.
