规范不变夸克格林函数的积分方程

Integral equation for gauge invariant quark Green's function

H. Sazdjian

摘要:

本文考虑了夸克规范不变的两点格林函数,其中胶子相因子沿斜折线变化。利用夸克传播子在外部胶子场存在下的一种特殊表示,建立了格林函数与不同折线段数之间的函数关系.积分方程得到的格林函数具有沿一条直线的相位因子。相关的内核涉及威尔逊圈与斜多边形轮廓和功能的衍生物沿轮廓的两侧。

英文摘要:

We consider gauge invariant quark two-point Green's functions in which the gluonic phase factor follows a skew-polygonal line. Using a particular representation for the quark propagator in the presence of an external gluon field, functional relations between Green's functions with different numbers of segments of the polygonal lines are established. An integral equation is obtained for the Green's function having a phase factor along a single straight line. The related kernels involve Wilson loops with skew-polygonal contours and with functional derivatives along the sides of the contours.
