ATLAS和CMS合作组都在寻找双喷流观测量中超越纯次领先阶的效应，目标是区分次领先阶加共线重算和广角硬发射重算所提供的微扰描述。在本文中，我们确定在dijet生产的相空间区域，其中一些可观的接收大的修正超过下一个领先的顺序和研究他们的理论描述与两个工具，执行这两个不同的recummations：thePOWHEG BOX和HEJ。此外，我们建议的分析，从POWHEG和HEJ的预测可以清楚地区分实验。
Both the ATLAS and CMS Collaborations have sought for effects beyond pure next-to-leading order in dijet observables, with the goal to distinguish between the perturbative descriptions provided by a next-to-leading order plus collinear-resummation calculation and by the resummation of wide-angle, hard emissions. In this paper, we identify regions of phase space in dijet production where some observables receive large corrections beyond next-to-leading order and study their theoretical description with two tools that perform these two different resummations: thePOWHEG BOXandHEJ. Furthermore, we suggest analyses where the predictions fromPOWHEGandHEJcan be clearly distinguished experimentally.
