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 WWγvertices at the one-loop level. We study these couplings, paying attention to the model-parameter and q2 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.
