TOP-QUARK DISTRIBUTIONS IN HADRONIC COLLISIONS

We present kinematical distributions for top quark pairs produced at t he Tevatron p $($) over bar$$ p Collider, as predicted within Next-to- leading-Order QCD. We consider single and double inclusive distributio ns, and compare our results to those obtained with the shower Monte Ca rlo HERWIG. We discuss the implications of our findings for experiment al issues such as the measurement of the top quark mass.
