The spin correlation in top quark production: QCD corrections vs anomalous couplings

Y. Kiyo, J. Kodaira, K. Morii, T. Nasuno, S. Parke

Published 2000-06-02Version 1

We discuss top quark production and its subsequent decay at lepton colliders including both QCD corrections and anomalous gamma / Z - t t-bar couplings. The off-diagonal spin basis for the top and anti-top quarks is shown to be useful to probe the anomalous couplings.
