标题： The Nucleon Energy Correlators

摘要： 我们引入了核子能量关联函数的概念，这是一组新的对象，它们编码了核子的微观细节，如核子中的部分子角分布、所有阶次的共线分裂以及核子内部的横向动力学。 核子能量关联函数补充了传统的核子/核子团成像，但无需引入非微扰的碎片化函数或喷注聚类算法。 我们展示了如何在轻子-核子深度非弹性散射中测量核子能量关联函数。 预测的分布显示出微扰和非微扰区域之间的迷人相变。 在微扰相中，预测了Bjorken标度行为的极角版本。 我们讨论了其可能的应用，并期望它能丰富带有远前向探测器的电子离子对撞机的物理内容。 显示英文摘要

摘要： We introduce the concept of the nucleon energy correlators, a set of novel objects that encode the microscopic details of a nucleon, such as the parton angular distribution in a nucleon, the collinear splitting to all orders, as well as the internal transverse dynamics of the nucleon. The nucleon energy correlators complement the conventional nucleon/nucleus tomography, but without introducing the non-perturbative fragmentation functions or the jet clustering algorithms. We demonstrate how the nucleon energy correlators can be measured in the lepton-nucleon deep inelastic scattering. The predicted distributions display a fascinating phase transition between the perturbative and non-perturbative regime. In the perturbative phase, a polar angle version of the Bjorken scaling behavior is predicted. We discuss its possible applications and expect it aggrandize the physics content at the electron ion colliders with a far-forward detector.
