Confinement studies in QCD with Dyson-Schwinger equations
arXiv:2011.12386 · doi:10.1016/j.nuclphysbps.2021.05.044
Abstract
We provide a study of quantum chromodynamics with the technique of Dyson-Schwinger equations in differential form. In this way, we are able to approach the non-perturbative limit and recover, with some approximations, the 't Hooft limit of the theory. Quark mass in the propagator term goes off-shell at low-energies signaling confinement. A condition for such occurrence in the theory is provided.
