Meson Effects on Chiral Condensate at Finite Density

Meson corrections on chiral condensate up to next-to-leading order in \(1/N_c\) expansion at finite density are investigated in NJL model with chiral symmetry explicitly breaking. Compared with the mean-field results, the chiral phase transition is still of first order, while the properties at the c...

Description
Summary:Meson corrections on chiral condensate up to next-to-leading order in \(1/N_c\) expansion at finite density are investigated in NJL model with chiral symmetry explicitly breaking. Compared with the mean-field results, the chiral phase transition is still of first order, while the properties at the critical density of chiral phase transition are found to change significantly.
