Flavor- and CP-violating physics from new supersymmetric thresholds.
Treating the minimal supersymmetric standard model as an effective theory, we study the implications of having dimension-five operators in the superpotential for flavor- and CP-violating processes, exploiting the linear decoupling of observable effects with respect to the new threshold scale c. We show that the assumption of weak-scale supersymmetry, when combined with the stringent limits on electric dipole moments and lepton-flavor-violating processes, provides sensitivity to Lambda as high as 10(7)-10(9) GeV (and up to 10(17) GeV through the theta term), while the next generation of experiments could directly probe the high-energy scales suggested by neutrino physics.
