标题： QCD Factorization from Light-ray OPE

摘要： 量子色动力学(QCD)中的能量-能量关联函数(EEC)是探测高能碰撞中喷注子结构的重要事件形状。 在理解共线极限方面取得了重大进展，其中两个探测器之间的角度趋近于零，这是从QCD的因子化公式和共形场理论中的光锥算符乘积展开(light-ray Operator Product Expansion, OPE)得出的。 在先前关于光锥算符重整化的研究基础上，我们采取了创新步骤，将光锥OPE扩展到非共形背景中，特别关注微扰QCD。 我们提出的光锥OPE形式受到三个基本性质的约束：洛伦兹对称性、重整化群不变性和来自物理可观测量的约束。 这种扩展使我们能够推导出EEC共线极限的因子化公式，从而促进对未来在共线极限中次主导幂修正的探索和理解。 显示英文摘要

摘要： The energy-energy correlator (EEC) in Quantum Chromodynamics (QCD) serves as an important event shape for probing the substructure of jets in high-energy collisions. A significant progress has been make in understanding the collinear limit, where the angle between two detectors approaches zero, from the factorization formula in QCD and the light-ray Operator Product Expansion (OPE) in Conformal Field Theory. Building upon prior research on the renormalization of light-ray operators, we take an innovative step to extend the light-ray OPE into non-conformal contexts, with a specific emphasis on perturbative QCD. Our proposed form of the light-ray OPE is constrained by three fundamental properties: Lorentz symmetry, renormalization group invariance, and constraints from physical observables. This extension allows us to derive a factorization formula for the collinear limit of EEC, facilitating the future exploration and understanding on subleading power corrections in collinear limit.
