In the B-LSSM the traditional mu-term dominates d_mu and d_tau while B-LSSM-specific CPV parameters also contribute, placing d_mu inside projected Phase-II sensitivity over substantial parameter space and allowing |d_tau| up to 10^{-21} e cm.

abstract
We study the electric dipole moment (EDM) and the anomalous magnetic dipole moment (MDM) of the muon in the CP-violating Minimal Supersymmetric extension of the Standard Model (MSSM). We take into account the contributions from the chargino- and neutralino-mediated one-loop graphs and the dominant two-loop Higgs-mediated Barr-Zee diagrams. We improve earlier calculations by incorporating CP-violating Higgs-boson mixing effects and the resummed threshold corrections to the Yukawa couplings of the charged leptons as well as that of the bottom quark. The analytic correlation between the muon EDM and MDM is explicitly presented at one- and two-loop levels and, through several numerical examples, we illustrate its dependence on the source of the dominant contributions. We have implemented the analytic expressions for the muon EDM and MDM in an updated version of the public code CPsuperH2.0.

The Muon and Tau Electric Dipole Moments in the B-L Supersymmetric Standard Model
