Exploring hybrid equation of state with constraints from tidal deformability of GW170817

Understand

With a interpolation method on the P-$\mu$ plane, a hybrid equation of state is explored.

• The quark phase is described by our newly developed self-consistent two-flavor Nambu$-$Jona-Lasinio model.
• It retains the contribution from the vector channel in the Fierz-transformed Lagrangian by introducing a weighting parameter $\alpha$ [Chin.
