论文摘要
我们介绍了PineAppl，这是一个生成物理横截面的快速交流网格的库，该网格使用通用的蒙特卡洛发生器计算，准确地固定在强，electroweak且结合的强势杆耦合中。我们证明了这种独特的能力，该功能通过将pineappl与文献中可用的类似软件区分开来，将其连接到Madgraph5_AMC@nlo。我们计算快速交流网格，以在强和电动轴耦合中准确到近后的序列，对于一组代表性的LHC过程，EW校正可能对相应理论预测的准确性具有很大的效果。我们为实验可交付成果的格式提出了建议，以将它们与包含EW校正的计算进行比较，并专门确定Parton分布函数，以相同的精度。
We introduce PineAPPL, a library that produces fast-interpolation grids of physical cross sections, computed with a general-purpose Monte Carlo generator, accurate to fixed order in the strong, electroweak, and combined strong-electroweak couplings. We demonstrate this unique ability, that distinguishes PineAPPL from similar software available in the literature, by interfacing it to MadGraph5_aMC@NLO. We compute fast-interpolation grids, accurate to next-to-leading order in the strong and electroweak couplings, for a representative set of LHC processes for which EW corrections may have a sizeable effect on the accuracy of the corresponding theoretical predictions. We formulate a recommendation on the format of the experimental deliverables in order to consistently compare them with computations that incorporate EW corrections, and specifically to determine parton distribution functions to the same accuracy.
