2 1 O ct 2 00 8 Quark mass dependence of thermal excitations in QCD in one-loop approximation

Abstract

Abstract. A comprehensive determination of the quark mass dependence in the dispersion relations of thermal excitations of gluons and quarks in non-Abelian gauge theory (QCD) is presented for the one-loop approximation in Feynman gauge. Larger values of the coupling are admitted, and the gauge dependence is discussed. In a Dyson-Schwinger type approach, the… (More)
