论文摘要
Drell-Yan的产量是LHC的精确基石之一，可作为诸如$ W $ -Boson质量之类的测量值的校准。它在1％挑战理论预测最高级别的1％水平上的极高精度。我们介绍了第一个在thressmentmentum（$ q_t $）重新召集的drell-yan生产的独立计算。我们的计算通过包含最近发表的四个环快速性异常维度和三个循环大规模轴向载体贡献来达到最新。我们将来自基准和差异横截面预测的CMS的最新数据进行比较，并在百分比上找到了良好的一致性。我们的重新召集计算包括NNLO的$ Z $+喷气生产的匹配，在即将到来的Cute-MCFM 10.3版本中公开可用，并允许在前所未有的级别上进行理论数据比较。
Drell-Yan production is one of the precision cornerstones of the LHC, serving as calibration for measurements such as the $W$-boson mass. Its extreme precision at the level of 1% challenges theory predictions at the highest level. We present the first independent calculation of Drell-Yan production at order $α_s^3$ in transverse-momentum ($q_T$) resummation improved perturbation theory. Our calculation reaches the state-of-the-art through inclusion of the recently published four loop rapidity anomalous dimension and three loop massive axial-vector contributions. We compare to the most recent data from CMS with fiducial and differential cross-section predictions and find excellent agreement at the percent level. Our resummed calculation including the matching to $Z$+jet production at NNLO is publicly available in the upcoming CuTe-MCFM 10.3 release and allows for theory-data comparison at an unprecedented level.
