    "abstract": "The chiral phase transition is studied in an extended Nambu--Jona-Lasinio\nmodel with eight-quark interactions. Equations for scalar and vector quark\ndensities, derived in the mean field approximation, are nonlinear and mutually\ncoupled. The scalar-type nonlinear term hastens the restoration of chiral\nsymmetry, while the scalar-vector mixing term makes the transition sharper. The\nscalar-type nonlinear term shifts the critical endpoint toward the values\npredicted by lattice QCD simulations and the QCD-like theory.",
