Supersymmetric Higgs singlet effects on FCNC observables

High Energy Physics - Phenomenology 2009-02-02 v1

Abstract

Higgs singlet superfields, usually present in extensions of the Minimal Supersymmetric Standard Model (MSSM) which address the μ\mu-problem, such as the Next-to-Minimal Supersymmetric Standard Model (NMSSM) and the Minimal Nonminimal Supersymmetric Standard Model (mnSSM), can have significant contributions to BB-meson flavour-changing neutral current observables for large values of tanβ\gsim50\tan\beta \gsim 50. Illustrative results are presented including effects on the BsB_s and on the rare decay Bsμ+μB_s\to\mu^+\mu^-. In particular, we find that in the NMSSM, the branching ratio for Bsμ+μB_s\to\mu^+\mu^- can be enhanced or even suppressed with respect to the Standard Model prediction by more than one order of magnitude.
