论文摘要
我们仔细检查了主要QED最终状态重新调整工具，并结合了Electroweak虚拟校正，以在四个充电的lepton最终状态下重现确切的近临界订单Electroweak计算。我们进一步研究了发现对Lepton-Photon敷料的依赖性以及共振策略。总体而言，我们发现与固定顺序结果有着极好的一致性，但是在某些情况下，观察到与重量％的高阶效应直接相关的部分差异与精确测量有关。
We scrutinise the ability of the primary QED final-state resummation tools, combined with electroweak virtual corrections, to reproduce the exact next-to-leading order electroweak calculation in the four-charged-lepton final state. We further examine the dependence of the findings on the lepton-photon dressing-cone size as well as the resonance identification strategy. Overall we find excellent agreement with the fixed-order result, but partial differences not directly connected with resummation-induced higher-order effects at the few-percent level are observed in some cases, which are relevant for precision measurements.
