Abstract
Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the -problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric Standard Model (mnSSM), can have significant contributions to -meson flavour-changing neutral current observables for large values of . Illustrative results are presented including effects on the and on the rare decay . In particular, we find that in the NMSSM, the branching ratio for can be enhanced or even suppressed with respect to the Standard Model prediction by more than one order of magnitude.
