Abstract
We consider the possibility of observing a parity-violating but CP-con serving interaction in the symmetry-breaking sector of the electroweak theory. We find that the best probe for such an interaction is a forw ard-backward asymmetry in W+W- production from polarized e(R)-e(L)+ co llisions. An observable asymmetry would be strong evidence against a c ustodial SU(2) symmetry. We also discuss the effects of such an intera ction in future e- gamma colliders as well as in rare decays of K and B mesons.
