Anomalous single production of fourth generation t′ quarks at ILC and CLIC

Abstract

We present a detailed study of the anomalous single fourth generation $t'$ 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 $t'q��$ and $t'qZ$ ($q=u,c$) anomalous couplings as well as values of attainable integrated luminosity for 3$��$ observation limit.12 pages, 14 figures, version to be published on Nucl.Phys.
