Abstract

We consider the possibility of observing a parity-violating but $CP$ -conserving interaction in the symmetry-breaking sector of the electroweak theory. We find that the best probe for such an interaction is a forward-backward asymmetry in $W^{+} W^{-}$ production from polarized $e_{R}^{-} e_{L}^{+}$ collisions. An observable asymmetry would be strong evidence against a custodial SU(2) symmetry. We also discuss the effects of such an interaction in future $e^{-} γ$ colliders as well as in rare decays of $K$ and $B$ mesons.
