The ghost-gluon vertex in Hamiltonian Yang-Mills theory in Coulomb gauge
arXiv:1111.5476 · doi:10.1016/j.physletb.2011.12.024
Abstract
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.
