Supersymmetric electromagnetic moments and radiation zeros

The radiative corrections to the electromagnetic moments of the charged gauge fermions and bosons (W and W) of the vector superfields are studied in unbroken supersymmetry. We find that supersymmetry does not force such corrections to vanish as it does for the charged spinor members of chiral supermultiplets. The implications of these results for radiation zeros are discussed. As an example, in an appendix we calculate the cross section for the process γe→Wnu-tilde/sub L/ (which has been studied previously by two groups with differing results) with anomalous W magnetic moment and show that radiation zeros exist in this process in the limit of vanishing anomalous W moments
