论文摘要
我们介绍了核子能量相关因子的概念，该核子能量相关因子是一组新的对象，它们编码了细胞核的显微镜细节，例如核子中的parton角分布，界线分裂为所有顺序，以及核子的内部横向动力学。核子能量相关器补充了常规的核子/核断层扫描，但没有引入非扰动片段化函数或喷气聚类算法。我们证明了如何在Lepton-Nucleon深度非弹性散射中测量核子能量相关因子。预测的分布显示了扰动和非扰动状态之间的引人入胜的相变。在扰动阶段，预测Bjorken缩放行为的极角版本。我们讨论其可能的应用，并期望它用遥远的检测器加重电子离子山脉的物理含量。
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.
