库仑规范下哈密顿Yang-Mills理论中的鬼胶子顶点

The ghost-gluon vertex in Hamiltonian Yang-Mills theory in Coulomb gauge

Davide R. Campagnari, Hugo Reinhardt

摘要:

本文用变分法中确定的非微扰鬼子和胶子传播子作为输入,在单圈水平上求解了库仑规范中Yang-Mills理论哈密顿方法中鬼胶子顶点的Dyson-Schwinger方程。得到的鬼胶子顶点是IR有限的,但IR增强相比,裸的15%至25%,这取决于运动学动量制度。

英文摘要:

The Dyson-Schwinger equation for the ghost-gluon vertex of the Hamiltonian approach to Yang-Mills theory in Coulomb gauge is solved at one-loop level using as input the non-perturbative ghost and gluon propagators previously determined within the variational approach. The obtained ghost-gluon vertex is IR finite but IR enhanced compared to the bare one by 15% to 25%, depending on the kinematical momentum regime.
