Abstract: An analysis of electroweak corrections to the anomalous dipole moments oflepton from some special two-loop diagrams where a closed neutralino-charginoloop is inserted into relevant one-loop diagrams of the standard model ispresented in the split supersymmetry scenarios. Considering the translationalinvariance of the inner loop momenta and the electromagnetic gauge invariance,we get all dimension 6 operators and their coefficients. After applyingequations of motion to the external leptons, we obtain the anomalous dipolemoments of lepton. The numerical results imply that there is parameter spacewhere the contribution to the muon anomalous magnetic dipole moment from thissector is perhaps significant, and the contribution to the electron electricdipole moment from this sector is sizable enough to be observed in nextgeneration experiments.
