Deconfining and chiral transitions of finitetemperature quantum chromodynamics in the presence of dynamical quark loops
Abstract
Finitetemperature behavior of quantum chromodynamics is investigated with the Langevin technique including the dynamical quark loops. The deconfining and chiral transitions occur at the same temperature. The strength of transition weakens initially as the quark mass decreases from infinity, but at small quark masses it strengthens again and shows the characteristic of a firstorder transition. We estimate the inverse coupling constant at zero quark mass to be beta_{c}=6/g^{2}_{c}~=4.95.0 for four flavors on an 8^{3}×4 lattice.
