Anomalous single production of fourth generation $t^{\prime }$ quarks at ILC and CLIC

Abstract

We present a detailed study of the anomalous single fourth generation $t^{\prime }$ quark production within the dominant Standard Model(SM) decay modes at future $e^{+}{e}^{-}$ colliders. We calculate the signal and background cross sections in the mass range 300-800 GeV. We also discuss the limits of $t^{\prime }q\gamma$ and $t^{\prime }qZ$ ($q=u,c$) anomalous couplings as well as values of attainable integrated luminosity for 3$\sigma$ observation limit.
