The spin correlation in top quark production: QCD corrections vs anomalous couplings
Y. Kiyo, J. Kodaira, K. Morii, T. Nasuno, S. Parke
Abstract
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.
