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. σ observation limit. © 2011 Elsevier B.V.
