摘要：

We discuss tensor correlations measurable in various reactions at LEP (or at future e+e- colliders) with which possible CP-violating effects can be disentangled from CP-even unitarity corrections. Moreover, we discuss questions of SU (2) x U (1) gauge invariance and various forms of effective lagrangians describing possible CP-violating effects at the Z resonance using as examples the decays Z --> l+l-, Z --> l+l-gamma.
