...ilable momentum range, however, is restricted from above by the lattice spacing and from below by the available lattice volume up to a further uncertainty related to so-called Gribov copies (see e.g. =-=[3]-=- and references therein). In recent years the DS / FRG framework has been applied also to explore the nonzero temperature regime of QCD and even the non-zero chemical potential case (see [4] and refer...
