H. Sazdjian

摘要:

在大N_c极限下,利用精确的积分微分方程,研究了二维QCD中的规范不变夸克格林函数。它被发现是红外有限的奇点表示的阈值类型的分支点的幂为-3/2,从积极的质量平方值。格林函数是解析确定的。

英文摘要:

The gauge invariant quark Green's function, defined with a path-ordered phase factor along a straight line, is studied in two-dimensional QCD in the large-N_c limit by means of an exact integrodifferential equation. It is found to be infrared finite with singularities represented by an infinite number of threshold type branch points with a power of -3/2, starting at positive mass squared values. The Green's function is analytically determined.
