New gauge boson and spin correction of top quark pair production at ILC

摘要

Based on the SU(3)simple group model,we study the spin correction of the top quark psir produetion at the high energy linear e+e-collider (ILC) with a center-of-mass energy √s =800GeV.Our numerical results show that the gauge boson Z(H) exchange generates very small corrections to the spin correction observable in all the parameter space,which can not be detected in the future ILC experiments.
