Abstract

We propose to embed the General NMSSM (Next-to-Minimal Supersymmetric Standard Model) into the deflected AMSB (Anomaly Mediated Supersymmetry Breaking) mechanism with Yukawa/gauge deflection contributions. After integrating out the heavy messenger fields, the analytical expressions of the relevant soft SUSY breaking spectrum for General NMSSM at the messenger scale can be calculated. We find that successful EWSB (Electroweak Symmetry Breaking) and realistic low energy NMSSM spectrum can be obtained in some parameter regions. In addition, we find that the muon g2g-2 anomaly and electron g2g-2 anomaly (for positive central value electron g2g-2 experimental data) can be jointly explained to 1σ1\sigma and 2σ2\sigma range, respectively. The Z3Z_3 invariant NMSSM, which corresponds to ξF=0\xi_F=0 in our case, can also jointly explain the muon and electron anomaly to 1σ1\sigma and 2σ2\sigma range, respectively.
