NJL model at finite temperature and chemical potential in dimensional regularization
Seminar Room 1, Newton Institute
We study the two-flavors Nambu--Jona-Lasinio (NJL) model at finite temperature and chemical potential by using the dimensional regularization. Since this model is non-renormalizable in four spacetime dimensions, physical results depend on the regularization method. We also discuss the color superconductivity in the extended NJL model by using the dimensional regularization.
