Angular correlations in top quark pair production and decay at hadron colliders

Abstract

We show how to observe sizable angular correlations between the decay products of the top quark and those of the top antiquark in top quark pair production and decay at hadron colliders. These correlations result from the large asymmetry in the rate for producing like-spin versus unlike-spin top quark pairs provided the appropriate spin axes are used. The effects of new physics at production or decay on these correlations are briefly discussed. \textcopyright{} 1996 The American Physical Society.
