In recent years, energy correlators have emerged as a powerful tool to explore the field theoretic structure of strong interactions at particle colliders. In this Letter we initiate a novel study of the nonperturbative power corrections to the projected N-point energy correlators in the limit where the angle between the detectors is small. Using the light-ray operator product expansion as a guiding principle, we derive the power corrections in terms of two nonperturbative quantities describing the fragmentation of quarks and gluons. In analogy with their perturbative leading-power counterpart, we show that power corrections obey a classical scaling behavior that is violated at the quantum level. This crucially results in a dependence on the hard scale Q of the problem that is calculable in perturbation theory. Our analytic predictions are successfully tested against Monte Carlo simulations for both lepton and hadron colliders, marking a significant step forward in the understanding of these observables.

Light-Ray Operator 产品扩展中对能量相关器的功率校正中的缩放违规


近年来，能量相关器已成为探索粒子对撞机强相互作用的场论结构的有力工具。在这封信中，我们开始了一项新的研究，即在探测器之间角度较小的极限内对投影的 N 点能量相关器进行非扰动功率校正。以光线算子积展开为指导原则，我们根据描述夸克和胶子碎裂的两个非扰动量推导出功率校正。与它们的扰动超前幂对应物类似，我们表明幂校正遵循在量子水平上违反的经典缩放行为。这关键地导致了对问题的硬尺度 Q 的依赖性，而该问题在微扰理论中是可计算的。我们的分析预测成功地针对轻子和强子对撞机的蒙特卡洛模拟进行了测试，这标志着在理解这些可观测物方面向前迈出了重要一步。 美国物理学会 2024 年出版
