We report the first calculation of fully differential jet production at leading color in all partonic channels at next-to-next-to leading order in perturbative QCD and compare to the available ATLAS 7 TeV data. We discuss the size and shape of the perturbative corrections along with their associated scale variation across a wide range in jet transverse momentum, p_{T}, and rapidity, y. We find significant effects, especially at low p_{T}, and discuss the possible implications for parton distribution function fits.
我们报告了在微扰量子色动力学中次下一个领头阶下，所有部分子通道中领头色全微分喷注产生的首次计算，并与现有的ATLAS 7 TeV数据进行比较。我们讨论了微扰修正的大小和形状，以及它们在喷注横向动量(p_{T})和快度(y)的广泛范围内相关的标度变化。我们发现了显著的效应，特别是在低(p_{T})时，并讨论了对部分子分布函数拟合的可能影响。
