Running coupling of 2-flavor QCD at zero and finite temperature

Abstract

We present lattice studies of the running coupling in 2-flavor QCD. The coupling at zero temperature (T=0) is extracted from Wilson loops while the coupling at finite temperature ($T\ne 0$) is determined from Polyakov loop correlation functions.
