Aspects of a non-local PNJL model with wave function renormalization

Results for thermodynamical properties of quark matter will be presented which are obtained within the framework of a two-flavor, non-local Polyakov-Nambu-Jona-Lasinio model which includes an interaction that produces the wave function renormalization (WFR) of the quark propagator. In the elaboration of the corresponding phase diagrams, special attention is devoted to the determination of the critical end points, by developing a system of equations that allows to calculate numerically the corresponding mean field values together with the precise location of the critical points. The values for critical exponents are examined. An outlook is given to the project pursued within a research visit at the University of Wroclaw.
