CP Violating Asymmetries in the Flavor Changing Single Top Quark Production

Abstract

CP violating effects in the single top quark production via flavour changing neutral current (FCNC) reactions $e^{+}{e}^{-}->tbarq$ and $e^{+}{e}^{-}->bartq$ (here $q$ refers to charm and up quarks) are studied. The effective Lagrangian description of the FCNC interactions is used. A numerical analysis is performed for some next linear colliders. CP violating asymmetries for the number of $q$ and $\bar{q}$ quarks are obtained to be of order $10^{-2}-10^{-3}$ depending on the CM energy.
