Signals For Parity Violation in the Electroweak Symmetry Breaking Sector

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 $e^{-}\gamma$ colliders as well as in rare decays of $K$ and $B$ mesons.
