Abstract
The supersymmetric standard model contains a new CP-violating phase in the mass matrices for charginos and neutralinos, which could induce CP-odd anomalous couplings for the WWZ and WW\gamma vertices at the one-loop level. We study these couplings, paying attention to the model-parameter and q^2 dependencies. It is shown that the CP-odd form factors could have values of order 10^{-3}-10^{-4}, which are much larger than those predicted by the standard model. We also discuss the possibility of examining these form factors in experiments.
