论文摘要
在本文中，我们着重于研究与时间反转转换有关的Lorentz参数化函数的功能复杂性。我们认为，非本地夸克（-gluon）运算符的相应相关器中编码的相互作用为参数化函数生成了其他功能复杂性来源，而文献中未讨论的参数化函数。我们还重新审查了由非本地运算符的强子基质元素给出的不同相关因子的洛伦兹参数化。已经提出了新的参数函数存在的证据。
In the paper we focus on the study of the functional complexity of the Lorentz parametrizing functions in connection with the time-reversal transformations. We argue that the interactions encoded in the corresponding correlators of non-local quark(-gluon) operators generate additional sources of functional complexity for the parametrizing functions which are not discussed in the literature. We also revisit the Lorentz parametrization of different correlators given by the hadron matrix elements of the non-local operators. The evidences for the new parametrizing function existence have been presented.
