Abstract
We present compact expressions for the amplitudes describing production and decay of heavy top-anti-top quark pairs in hadron-hadron collisions. We include both the effects of a finite width of the W particles in the top quark decay and those of a non-zerob quark mass, as well as the complete spin correlations in the decays. Also a very compact analytical result for the width of the top quark including all these effects is given.
