Description
CP-violating asymmetries calculated from the Breit-Wigner approximation for unstable particle propagators violate CPT invariance. A formalism satisfying CPT invariance and unitarity is presented. Applications are given to t decays. For the decay t→bντ bar τ in a class of CP-violating Higgs models the CP-violating asymmetry turns out to be 10-4 times smaller than the previously reported results
