摘要：
The production of a t (t) over bar pair and its decay into a six fermion final state of different flavors in c(+)c(-) annihilation at center of mass energies typical for linear colliders is analyzed in the framework of the standard model. The results of a calculation based on exact matrix elements at the tree level and full six particle phase space are compared with a few different approximations. It is shown that the effects related to off-shellness of the t (t) over bar pair and background contributions are sizable both in the continuum and at the threshold.
