Quark pairing in sQGP

We obtain a quark pairing gap in sQGP by solving the coupled Dyson-Schwinger equations for quark propagator and quark gluon vertex in the Nambu-Gorkov basis which is widely applied to study the color superconductivity. We acquire a quark pairing gap at small chemical potential which is related to the dimension two gluon condensate and hence, its generation mechanism differs from the conventional color superconducting phase located only at large chemical potential. The gap persists up to 2 − 3 T_c and vanishes at higher temperature. Such a quark pairing together with a second order phase transition characterizes a partial-deconfined new phase in sQGP and distinct from the phase with quasi quarks and gluons.
