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.
