Abstract
The most general form of the WWZ and WW gamma interaction contains a C P-violating term which has the same threshold behaviour as the Standar d Model e(+)e(-) --> W+W- cross section. We calculate the cross sectio n as a function of the corresponding anomalous coupling, and estimate the bounds which can be obtained from a measurement of the threshold c ross section at LEP2. We show how the effect of the coupling is most p ronounced in the angular distributions of the final-state fermions.
