本文考虑一阶形式的微扰库仑规范杨-米尔斯理论。利用微分方程技术和维数正则化，解析结果的紫外发散和有限的两点函数在一个循环的顺序。它示出了如何的非紫外发散部分的结果是有限的类空动量与运动学奇异的光锥和随后的分支削减延伸到类时区域。
Perturbative Coulomb gauge Yang-Mills theory within the first order formalism is considered. Using a differential equation technique and dimensional regularization, analytic results for both the ultraviolet divergent and finite parts of the two-point functions at one-loop order are derived. It is shown how the nonultraviolet divergent parts of the results are finite at spacelike momenta with kinematical singularities on the light-cone and subsequent branch cuts extending into the timelike region.
