Constraining a CP-violating WWV coupling from the W^+W^- threshold cross section at LEP2
The most general form of the and interaction contains a
-violating term which has the same threshold behaviour as the Standard
Model \ee \to \ww cross section. We calculate the cross section as a function
of the corresponding anomalous coupling, and estimate the bounds which can be
obtained from a measurement of the threshold cross section at LEP2. We show how
the effect of the coupling is most pronounced in the angular distributions of
the final-state fermions.Comment: 7 pages, LaTeX file, 5 ps figure
