本文计算了强子碰撞中顶-反顶对产生的次-首阶（NNNLO）软胶子修正。通过在完整的次-次-首阶（NNLO）截面上加入NNNLO软胶子修正，得到了近似的NNNLO（aNNNLO）结果.理论预测显示在LHC和Tevatron能量的总aNNNLO $t\overline {t}$截面。aNNNLO截面比NNLO截面大，但理论不确定性较小。
I present a calculation of next-to-next-to-next-to-leading-order (NNNLO) soft-gluon corrections for top-antitop pair production in hadronic collisions. Approximate NNNLO (aNNNLO) results are obtained by adding the NNNLO soft-gluon corrections to the complete next-to-next-to-leading-order (NNLO) cross section. Theoretical predictions are shown for the total aNNNLO $t\overline{t}$ cross section at LHC and Tevatron energies. The aNNNLO cross sections are larger but have smaller theoretical uncertainties than at NNLO.
