CP Violation in Semileptonic $\tau$ Decays with Unpolarized Beams

Abstract

CP violating signals in semileptonic $\tau$ decays are studied. These can be observed in decays of unpolarized single $\tau$'s even if their rest frame cannot be reconstructed. No beam polarization is required. The importance of the two meson channel, in particular the $K\pi$ final state is emphasized.
