The production of a tt pair and its decay into a six fermion
final state
of different flavors in e+e- 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 pair and background
contributions
are sizable both in the continuum and at the threshold.
