摘要：

Due to tau-polarimetry, on-going experiments with unpolarized e-e+ collisions enable four distinct tests for CP/T violation in Z0 --> tau--tau+, and in gamma* --> tau--tau+. Nine measurable (slashed/primed) vertex intensity parameters are useful signatures for CP/T violation respectively. Should such signature(s) be discovered, vertex intensity relations can be used as a check and to characterize the effect in terms of the polar parametrization of the Z0 --> tau--tau+ or gamma* --> tau--tau+, helicity amplitudes.
