Abstract

We explain our imaginary chemical potential matching approach as a reliable method to quantitatively investigate the QCD phase diagram at finite real chemical potential. In our approach, we consider the imaginary chemical potential region as a space to determine the parameter set of effective models. The two- and three-flavor systems are investigated by using the Polyakov-loop extended Nambu-Jona-Lasinio model.
