CP Violation in Semileptonic $τ$ Decays with Unpolarized Beams

Abstract

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