The chiral crossover, static-light and light-light meson spectra, and the deconfinement crossover

Abstract

We study the chiral crossover, the spectra of light-light an d of static-light mesons and the deconfinement crossover at finite temperature T. Our framework is t he confining and chiral invariant quark model, related to truncated Coulomb gauge QCD. Since we are dealing with light quarks, where the linear potential dominates the quark condensate and the spectrum, we only specialize in the linear confining potential for the quark-antiquark in teraction. We utilize T dependent string tensions previously fitted from lattice QCD data, and a fit of p reviously computed dynamically generated constituent quark masses. We scan the T effects on the constituent quark mass, on the meson spectra and on the polyakov loop.
