T Hooft极限下QCD中的夸克禁闭

Quark confinement in QCD in the 't Hooft limit

Marco Frasca, Anish Ghoshal, Stefan Groote

摘要:

我们处理量子色动力学(QCD)使用一组Dyson-Schwinger方程导出,在微分形式,与Bender-Milton-Savage技术。通过这种方式,我们能够推导出假设非局部Nambu-Jona-Lasinio模型形式的低能量极限。相应的能隙方程的研究表明,这样的模型没有自由夸克在低能极限。

英文摘要:

We treat quantum chromodynamics (QCD) using a set of Dyson-Schwinger equations derived, in differential form, with the Bender-Milton-Savage technique. In this way, we are able to derive the low energy limit that assumes the form of a non-local Nambu-Jona-Lasinio model. The corresponding gap equation is then studied to show that such a model has no free quarks in the low-energy limit.
