Anomalous quadrupole moment ofWin supersymmetry

We consider the radiative corrections to the anomalous quadrupole moment of the charged gauge boson W in supersymmetric SU(2${)}_L$×U(1${)}_Y$ theory. The results are finite and do not vanish contrary to the well-known result that radiative corrections to the lepton g-2 vanish identically in unbroken supersymmetry. Finally, the effects of spontaneously broken supersymmetry in a simple model with two Higgs doublets are discussed.
