BEC-BCS crossover in the NJL model of QCD

The phenomenon of BEC-BCS crossover occurs in dense, strongly correlated Fermi systems and has recently been discussed for cold dense quark matter systems. We consider this phenomenon for the two- and three-color NJL model with scalar-pseudoscalar mesonic and scalar diquark correlations in dependence on the diquark coupling strength. The effect of the inclusion of the vector-axial vector meson sector is investigated. For applications to compact stars the constraint of color- and electric neutrality need to be considered while for heavy-ion collisions, an extension to finite temperatures is necessary.
