标题： Energy-momentum tensor of the nucleon on the light front: Abel tomography case

摘要： 我们研究了在光锥上核子的二维能量动量张量（EMT）分布，使用三维EMT的阿贝尔变换。 我们明确展示了所有EMT分布的主要特征在阿贝尔变换过程中保持不变。 我们还检查了三维布雷特框架和光锥上的二维横向平面上核子稳定性的全局条件和局部条件之间的等价性。 我们还讨论了光锥上核子内部的二维力场。 显示英文摘要

摘要： We investigate the two-dimensional energy-momentum-tensor (EMT) distributions of the nucleon on the light front, using the Abel transforms of the three-dimensional EMT ones. We explicitly show that the main features of all EMT distributions are kept intact in the course of the Abel transform. We also examine the equivalence between the global and local conditions for the nucleon stability in the three-dimensional Breit frame and in the two-dimensional transverse plane on the light front. We also discuss the two-dimensional force fields inside a nucleon on the light front.
