Relation Between Chiral Susceptibility and Solutions of Gap Equation in Nambu--Jona-Lasinio Model
Yue Zhao, Lei Chang, Wei Yuan +1
We study the solutions of the gap equation, the thermodynamic potential and the chiral susceptibility in and beyond the chiral limit at finite chemical potential in the Nambu--Jona…
On the Consistency of the Ladder Approximation and the Rainbow Approximation of Dyson-Schwinger Equation of QCD
Lei Chang, Yu-xin Liu
We study the consistency of the ladder approximation and the rainbow approximation of the Dyson-Schwinger equation of QCD. By considering the non-Abelian property of QCD, we show t…
Dynamical chiral symmetry breaking and a critical mass
Lei Chang, Yu-Xin Liu, Mandar S. Bhagwat +2
On a bounded, measurable domain of non-negative current-quark mass, realistic models of QCD's gap equation can simultaneously admit two inequivalent dynamical chiral symmetry break…
Soliton with a Pion Field in the Global Color Symmetry Model
Bin Wang, Hui-chao Song, Lei Chang +2
We calculate the property of the global color symmetry model soliton with the pion field being included explicitly. The calculated results indicate that the pion field provides a s…
Phase Transition of Finite Size Quark Droplets with Isospin Chemical Potential in the Nanbu--Jona-Lasinio Model
Guo-yun Shao, Lei Chang, Yu-xin Liu +1
Making use of the NJL model and the multiple reflection expansion pproximation, we study the phase transition of the finite size droplet with u and d quarks. We find that the dynam…
