摘要：

We study the effects of possible C- and P-conserving anomalous couplings in the trilinear gauge vertex WWZ in the process e+e- --> Z0-nu-nu-BAR. Total cross sections and distributions for various square-root s are computed versus the anomalous eta(Z) (= kappa(Z) - 1) and lambda(Z) couplings by means of the analytic expression for E(Z)(d3-sigma/dp(Z)). An explicit expression for sigma(eta(Z), lambda(Z)) is given at different square-root s. Limits on eta(Z) and lambda(Z) that can be put at future e+e- colliders on the basis of the reaction e+e- --> Z0-nu-nu-BAR are discussed.
