Chiral phase transition and color superconductivity in an extended NJL model with higher-order multi-quark interactions
K. Kashiwa, H. Kouno, T. Sakaguchi +2
The chiral phase transition and color superconductivity in an extended NJL model with eight-quark interactions are studied. The scalar-type nonlinear term hastens the chiral phase…

Auxiliary Field Meson Model at Finite Temperature and Density
H. Kouno, T. Sakaguchi, K. Kashiwa +4
Starting from many quark interactions, we construct a nonlinear sigma-omega model at finite temperature and density. The mesons are introduced as auxiliary fields. Effective quark-…
