Abstract

A well-known feature of supersymmetry is that there are flavour-changing strong interactions mediated by gluinos. We calculate the effective Zd̅s coupling due to this interaction taking into account the constraints on the relevant parameters from CP-violation data. The consequences on the branching ratio for KL→μμ̅ and the CP-violating muon polarisation asymmetry are examined. The effects are found to be rather small and within experimentally acceptable limits.
