This restricts the region for the critical endpoint in the QCD phase diagram and stiffens the quark matter equation of state (EoS). It is demonstrated that the construction of a hybrid EoS for compact star applications within a two-phase approach employing the nonlocal PNJL EoS and an advanced hadronic EoS leads to the masquerade problem. As a possible solution the construction of a unified quark-hadron matter description is outlined which follows from a beyond meanfield approach [1] S. Noguera and N. N. Scoccola, Phys. Rev.
