论文摘要
提出了一个实验程序,以对差分横截面进行测量,以提高准确性,可以将其与固定排正常的QCD预测进行比较。该过程可以应用于玻色子横向动量中不同的DREL-YAN横截面测量值。使用Atlas测量$ Z $ -Boson生产横截面的Atlas测量,以$ 8 $ TEV进行进行分析。将玻色子速度中横截面差异的全相空间测量与QCD中近代到接头的前阶精度计算的理论预测进行了比较。
An experimental procedure is proposed to perform measurements of differential cross sections which can be compared to fixed-order QCD predictions with improved accuracy. The procedure can be applied to the Drell-Yan cross-section measurements which are differential in the boson transverse momentum. An example analysis is performed using the ATLAS measurement of the $Z$-boson production cross section at center-of-mass energy of $8$ TeV. The resulting full phase space measurement of the cross section differential in the boson rapidity is compared to theoretical predictions computed with next-to-next-to leading-order accuracy in QCD.
