Regularization dependence on phase diagram in Nambu-Jona-Lasinio model
T. Inagaki, D. Kimura, H. Kohyama
We study the regularization dependence on meson properties and the phase diagram of quark matter by using the two flavor Nambu-Jona-Lasinio model. We find that the meson properties…
Next to leading order calculation with dimensional regularization in Nambu--Jona-Lasinio Model
T. Inagaki, D. Kimura, H. Kohyama
The Nambu--Jona-Lasinio model is investigated in the expansion with the dimensional regularization. At the four-dimensional limit the meson propagators have simple forms in…
Regularization parameter independent analysis in Nambu-Jona-Lasinio model
T. Inagaki, D. Kimura, H. Kohyama +1
Nambu-Jona-Lasinio model used to investigate low energy phenomena is nonrenormalizable, therefore the results depend on the regularization parameter in general. A possibility of th…
Phase diagram of Nambu-Jona-Lasinio model with dimensional regularization
T. Inagaki, D. Kimura, H. Kohyama +1
We investigate the phase diagram on temperature-chemical potential plane in the Nambu-Jona-Lasinio model with the dimensional regularization. While the structure of the resulting d…
High density quark matter in the NJL model with dimensional vs. cut-off regularization
T. Fujihara, D. Kimura, T. Inagaki +1
We investigate color superconducting phase at high density in the extended Nambu--Jona-Lasinio model for the two flavor quarks. Because of the non-renormalizability of the model, p…
A Soluble Model of Four-Fermion Interactions in de Sitter Space
T. Inagaki, S. Mukaigawa, T. Muta
We consider the theory of four-fermion interactions with N-component fermions in de Sitter space. It is found that the effective potential for a composite operator in the theory is…
