论文摘要
通过采用局部QFT框架，一个人可以以非扰动方式得出，庞加莱对称对洛伦兹协变量分解中出现的形式施加的约束对能量momentum张量矩阵元素的分解。特别是，这种方法使人们能够证明这些约束实际上与矩阵元素中出现的状态的内部属性无关。在这里，我们概述了这种方法背后的基本原理，并报告了这些发现的某些含义。
By adopting a local QFT framework one can derive in a non-perturbative manner the constraints imposed by Poincaré symmetry on the form factors appearing in the Lorentz covariant decomposition of the energy-momentum tensor matrix elements. In particular, this approach enables one to prove that these constraints are in fact independent of the internal properties of the states appearing in the matrix elements. Here we outline the rationale behind this approach, and report on some of the implications of these findings.
