强子对撞机上胶子对产生的QCD阈值修正

QCD threshold corrections for gluino pair production at hadron colliders

Ulrich Langenfeld, Sven-Olaf Moch, Torsten Pfoh

摘要:

本文给出了次领先阶强子对撞机上胶子对产生总截面的QCD阈值增强预言。由于所需的单循环硬匹配系数的计算,我们的结果是准确的下一个到下一个到领先的对数。在一个简短的唯象研究中,我们提供了在大型强子对撞机的总强子截面的预测,我们讨论了由标度变化和部分子分布函数所产生的不确定性。

英文摘要:

We present the complete threshold enhanced predictions in QCD for the total cross section of gluino pair production at hadron colliders at next-to-next-to-leading order. Thanks to the computation of the required one-loop hard matching coefficients our results are accurate to the next-to-next-to-leading logarithm. In a brief phenomenological study we provide predictions for the total hadronic cross sections at the LHC and we discuss the uncertainties arising from scale variations and the parton distribution functions.
