部分子分布:函数复杂性和Lorentz参数化

Parton distributions: Functional complexity and Lorentz parametrization

I. V. Anikin, L. Szymanowski

摘要:

本文着重研究了与时间反演变换有关的洛伦兹参数化函数的函数复杂性。我们认为,编码在相应的非本地夸克(胶子)运营商的相互作用产生额外的来源的参数化功能的功能复杂性,这是没有在文献中讨论。我们还重新讨论了由非定域算符的强子矩阵元给出的不同算符的Lorentz参数化。给出了新参数化函数存在的证据。

英文摘要:

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.
