AI 中文摘要
我们研究小角度下的近侧能量-能量关联函数（EECs），通过 Mellin 变换框架在微扰和禁闭后区域明确纳入 QCD 标度行为。作为示例，我们表明，表征两个区域间转变尺度的单个参数 Λ，能以次下-次领头阶精度和次下-次领头对数重求和，出色地描述 $e^+e^-$ 湮灭中的近侧 EECs，涵盖近期 ALEPH 分析及不同能量下的早期测量。
英文摘要
We investigate nearside energy-energy correlators (EECs) at small angles, explicitly incorporating the QCD scaling behavior in both the perturbative and post-confinement regimes through a Mellin-transform framework. As an illustration, we show that a single parameter, $Λ$, characterizing the transition scale between the two regimes, provides an excellent description of nearside EECs in $e^+e^-$ annihilation, including the recent ALEPH analysis as well as earlier measurements across different energies, with next-to-next-to-leading-order accuracy and next-to-next-to-leading-logarithmic resummation.
