Decay-lepton angular distribution in polarized $e^{+}{e}^{-}\to$ and $CP$-violating dipole couplings of the top quark

P. Poulose, Saurabh D. Rindani

In the presence of an electric dipole coupling of $t\bar{t}$ to a photon, and an analogous ``weak" dipole coupling to the $Z$, $CP$ violation in the process $e^+e^- \rightarrow t \…
