Chiral phase transition and color superconductivity in an extended NJL model with higher-order multi-quark interactions
arXiv:nucl-th/0612038
Abstract
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 transition,the scalar-vector mixing term suppresses effects of the vector-type linear term and the scalar-diquark mixing term makes the coexisting phase wider.
