论文摘要
我们提出了一个六维的光较高的wigner分布，以通过Miller和Brodsky的最近提出的光线变量$ \ tilde {Z} $的优势，以完整描述强子（如斜向和质子）的党结构。从Wigner分布得出的数量包含党结构的最通用信息，包括将纵向坐标与横向动量或横向坐标的新数量以及旋转。新的Wigner分布可以看作是强子物理学中原始Wigner分布的相对论版，并且可以广泛使用了五维光线的Wigner分布。
We propose a six-dimensional light-front Wigner distribution for the complete description of partonic structures of a hadron such as pion and proton, taking advantage of the recently proposed light-front variable $\tilde{z}$ by Miller and Brodsky. Quantities derived from the Wigner distribution contain the most general information of partonic structures, including also new quantities correlating longitudinal coordinate with transverse momenta or transverse coordinates, together with spins. The new Wigner distribution can be viewed as a relativistic version of the original Wigner distribution in hadron physics and an extension of widely utilized five-dimensional light-front Wigner distribution.
