Dependence of the crossover zone on the regularization method in the two-flavor Nambu–Jona-Lasinio model

Dependence of the crossover zone on the regularization method in the two-flavor Nambu–Jona-Lasinio model

In this article, we study the two-flavor Nambu and Jona-Lasinio (NJL) phase diagrams on the T–μ plane through three regularization methods. In one of these, we introduce an infrared three-momentum cutoff in addition to the usual ultraviolet regularization to the quark loop integrals and compare the...
