   <hidden TTP98-10  Top quark production at threshold with  O(alpha_s^2) accuracy > We calculate the next-to-next-to-leading order
 correction to the cross section for top quark pair production
 in e+e- annihilation in the threshold region, resumming all
 O [ ( alpha_s/beta )^n ( alpha_s^2, beta^2, alpha_s beta ) ]
 terms of perturbation series. We find that the magnitude of
 the NNLO correction is comparable to the size of the NLO
 corrections.
