摘要

我们提出了量子色动力学(QCD)事件形状在次领先阶电子-正电子湮灭(NLO)中可观察到的能量-能量相关的第一个完全解析计算。这一结果揭示了超越领先顺序(LO)的事件形状可观测值的分析结构，并作为将我们的方法应用于迄今尚未进行分析计算的其他事件形状可观测值的研究的动机。

NLO QCD Energy-Energy-Correlation in $e^+ e^-$ Annihilation

We present the first fully analytic calculation of the Quantum Chromodynamics (QCD) event shape observable Energy-Energy Correlation in electron-positron annihilation at Next-To-Leading Order (NLO). This result sheds light on the analytic structure of the event shape observables beyond Leading Order (LO) and serves as a motivation to employ our methods in the investigation of other event shape observables that so far have not been calculated analytically.
