摘要：

We discuss the heavy quark production cross section near partonic threshold in hadronic collisions, including the resummation of leading and next-to-leading logarithms arising from soft gluon emission. We show how to handle the complications due to the non-universal non-leading logarithms. We give analytical results for the q (q) over bar partonic subprocess and numerical results in the DIS scheme for top quark production at the Fermilab Tevatron where the q (q) over bar channel dominates.
