CP Violation from Charged Higgs Exchange in Hadronic Tau Decays with Unpolarized Beams

Abstract

CP violating signals in semileptonic $\tau$ decays induced by an exotic scalar exchange are studied in a completely model-independent way. 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.
