标题： Confinement studies in QCD with Dyson-Schwinger equations

摘要： 我们提供了一项利用微分形式的Dyson-Schwinger方程技术对量子色动力学的研究。 通过这种方式，我们能够接近非微扰极限，并在一些近似下恢复该理论的't Hooft极限。 传播子项中的夸克质量在低能下脱离壳，表明了禁闭现象。 给出了该现象在理论中出现的条件。 显示英文摘要

摘要： 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.
