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…
Chiral phase transition in an extended NJL model with higher-order multi-quark interactions
Kouji Kashiwa, Hiroaki Kouno, Tomohiko Sakaguchi +2
The chiral phase transition is studied in an extended Nambu--Jona-Lasinio model with eight-quark interactions. Equations for scalar and vector quark densities, derived in the mean…
Meson loop effect on high density chiral phase transition
Tomohiko Sakaguchi, Kouji Kashiwa, Masayuki Matsuzaki +2
We test the stability of the mean-field solution in the Nambu--Jona-Lasinio model. For stable solutions with respect to both the σand πdirections, we investigate effects of the mes…
The Auxiliary Field Method in Quantum Mechanical Four-Fermi Models -- A Study Toward Chiral Condensation in QED
Taro Kashiwa, Tomohiko Sakaguchi
A study for checking validity of the auxiliary field method (AFM) is made in quantum mechanical four-fermi models which act as a prototype of models for chiral symmetry breaking in…
