Top Pair Production at Threshold and Effective Theories

Abstract

I give an introduction to the effective field theory description of top pair production at threshold in e+e- annihilation. The impact of the summation of logarithms of the top quark velocity including most recent results at next-to-next-to-leading logarithmic order is discussed.
