Lattice-QCD based Schwinger-Dyson approach for Chiral Phase Transition

Subject hep-ph
AbstractDynamical chiral-symmetry breaking in QCD is studied with the Schwinger-Dyson (SD) formalism based on lattice QCD data, i.e., LQCD-based SD formalism. We extract the SD kernel function $K(p^2)$ in an Ansatz-independent manner from the lattice data of the quark propagator in the Landau gauge. As remarkable features, we find infrared vanishing and intermediate enhancement of the SD kernel function $K(p^2)$. We apply the LQCD-based SD equation to thermal QCD with the quark chemical potential $mu_q$. We find chiral symmetry restoration at $T_c simeq 100{ m MeV}$ for $mu_q=0$. The real part of the quark mass function decreases as $T$ and $mu_q$. At finite density, there appears the imaginary part of the quark mass function, which would lead to the width broadening of hadrons.
