Towards high precision predictions for top quark pair production and decay at a linear collider

Abstract

We report on the progress in work on improving precision of the standard model theoretical predictions for the top quark pair production and decay into six fermions at a linear collider. Two programs have been combined into a single Monte Carlo program: 'eett6f', a MC program for e+e- -> 6f, and 'topfit', a program for electroweak radiative corrections to e+e- -> t\bar t. The MC program is described and preliminary numerical results are shown.
