规范轨道与库仑势

Gauge Orbits and the Coulomb Potential

J. Greensite

摘要:

如果色库仑势是封闭的,那么在无限晶格上孤立色电荷的库仑场能量是无限的,即使通常的UV发散是晶格调节的。库仑禁闭的一个简单判据是类时连接变量的期望值在库仑规范中为零,但这个判据与相应的Faddeev-Popov算符的谱之间的关系还不清楚,这可以用来制定一个完全不同的库仑禁闭判据。本文的目的是将两个看似不同的库仑约束准则联系起来,并解释这种联系的几何基础。

英文摘要:

If the color Coulomb potential is confining, then the Coulomb field energy of an isolated color charge is infinite on an infinite lattice, even if the usual UV divergence is lattice regulated. A simple criterion for Coulomb confinement is that the expectation value of timelike link variables vanishes in Coulomb gauge, but it is unclear how this criterion is related to the spectrum of the corresponding Faddeev-Popov operator, which can be used to formulate a quite different criterion for Coulomb confinement. The purpose of this article is to connect the two seemingly different Coulomb confinement criteria, and explain the geometrical basis of the connection.
