Abstract
The supersymmetric standard model contains a new CP-violating phase in the mass matrices for charginos and neutralinos, which could induce C P-odd anomalous couplings for the WWZ and WW gamma vertices at the one -loop level. We study these couplings, paying attention to the model-p arameter and q(2) dependencies. It is shown that the CP-odd form facto rs could have values of order 10(-3) - 10(-4), which are much larger t han those predicted by the standard model. We also discuss the possibi lity of examining these form factors in experiments.
