Description
In the present work, we study the phase diagram in the $T$−$\mu_{B}$ plane, in the frame of a non-local NJL model with a Gaussian form factor that depends on the spatial components of the momentum (3D-FF), which is fitted to lattice QCD results in the Coulomb gauge. We considered two light quark flavors, diquarks, and vector interactions. Hybrid EOS are obtained by a Maxwell construction of the first-order phase transition between a hadronic phase described by the relativistic density-dependent EOS with excluded volume effects. To simultaneously fulfill the constraints from the NICER radius measurement for PSR J0740+6620, its Shapiro delay maximum mass determination, and tidal deformability from GW170817, it is necessary to consider a $\mu_{B}$-dependent bag pressure that mimics confinement in the quark model.
