Query: Temperature dependence of meson screening masses; a comparison of
  effective model with lattice QCD   Temperature dependence of pion and sigma-meson screening masses is evaluated
by the Polyakov-loop extended Nambu--Jona-Lasinio model with the entanglement
vertex (EPNJL model). We propose a practical way of calculating meson screening
masses in the NJL-type effective models. The method based on the Pauli-Villars
regularization solves the well-known difficulty that the evaluation of
screening masses is not easy in the NJL-type effective models. The method is
applied to analyze temperature dependence of pion screening masses calculated
with state-of-the-art lattice simulations with success in reproducing the
lattice QCD results. We predict the temperature dependence of pole mass by
using EPNJL model.
