SUSY Effects (or Lack Thereof) in ΔF = 2 Transitions
I give a short account of the effects one expects on meson-antimeson oscillations in the context of the Minimal Supersymmetric Standard Model (MSSM). This issue is largely dependent on the assumptions made on the MSSM parameter space. In this respect, I consider in closer detail the cases of the general MSSM, with completely free soft terms, and the Minimal Flavor Violating limit of the MSSM. The latter case, characterized by a SM-like mechanism of near-flavor-conservation, predicts naturally small effects (below present errors) for low tan β. A similar, somehow weaker, conclusion holds for large tan β as well, once the constraint on the unobserved B s → μ + μ − decay is taken into account.
