Constraints from the Muon g-2 on the Parameter Space of the NMSSM

Abstract

We generalize the computation of supersymmetric contributions to the muon anomalous magnetic moment (g-2)_mu to the NMSSM. In the presence of a light CP-odd Higgs scalar, these can differ considerably from the MSSM. We discuss the amount of these contributions in regions of the parameter space of the general NMSSM compatible with constraints from B physics. In the mSUGRA-like cNMSSM, constraints from (g-2)_mu prefer regions in parameter space corresponding to a low SUSY breaking scale.
