TTP95-11 Top Quarks

Recent theoretical results on the production and decay of top quarks are presented. The implications of the new experimental results from the TEVATRON are briefly discussed. Predictions for the top quark decay rate and distributions are described, including the influence of QCD and electroweak radiative corrections. Top production at an $e^+e^-$ collider is discussed with emphasis towards the threshold region. The polarization of top quarks in the threshold region is calculated with techniques based on Green's functions for $S$ and $P$ waves.
