Description
The Nambu Jona-Lasinio (NJL) model is one of the useful models of Quantum chromodynamics, and it describes observed meson properties nicely. In this talk, we study the nonet meson properties by using the NJL model with dimensional regularization at finite temperature and chemical potential. We find that the results of the meson properties show reasonable behaviors, which are similar to the ones obtained in the model with the frequently used cutoff regularization. This may indicate that the model predictions are not drastically affected by the difference between the regularization procedures in the NJL model.
