我们确定了对{italp {barp}}碰撞中产生的方-反夸克对的次领先阶QCD修正。重整化尺度的依赖性大大降低。在费米实验室Tevatron的生产截面增加了约2倍，如果我们比较的下一个领先的顺序预测在一个规模附近的夸克质量与最低的顺序，在实验分析中，该规模被确定与不变的能量的部分中子过程。这导致费米实验室兆电子伏特加速器的嘎嘎声质量的实验下限上升了约20 GeV。
We have determined the next-to-leading order QCD corrections to the production of squark-antisquark pairs in {ital p{bar p}} collisions. The renormalization scale dependence is reduced considerably. The production cross section at the Fermilab Tevatron increases by about a factor of 2 if we compare the next-to-leading order prediction at a scale near the squark mass with the lowest order for which, in the experimental analyses, the scale was identified with the invariant energy of the parton subprocesses. This results in a rise of the experimental lower bound on the squark mass from the Fermilab Tevatron by about 20 GeV.
