What rare K decays can tell about the MSSM

TL;DR

This paper reviews how rare K meson decays can provide insights into the flavor structure of the Minimal Supersymmetric Standard Model (MSSM) by analyzing four specific decay modes.

Contribution

It offers a concise review of supersymmetric effects on rare K decays and highlights the potential of combined measurements to probe MSSM flavor parameters.

Findings

Supersymmetric contributions significantly affect rare K decay rates.

Combined analysis of four decay modes enhances MSSM flavor sector understanding.

Theoretical predictions for these decays are clean and precise.

Abstract

The supersymmetric contributions to the theoretically clean K+ --> pi+ nu nu bar, KL --> pi0 nu nu bar, KL --> pi0 e+ e- and KL --> pi0 mu+ mu- decays are briefly reviewed. Particular emphasis is laid on the information one could get on the MSSM flavor sector from a combined study of the four modes.
