Fisher's zeros for SU(3) with Nf flavors and RG flows

Abstract

We calculate the Fisher zeros for SU(3) gauge theory with N f = 4, 8 and 12 flavors of staggered fermions for various values of the fermion mass. We discuss the finite-size scaling near the end point of the line of discontinuity ofψψ in the beta-mass plane and in the larger beta-lower mass region. We discuss possible interpretations of these results in terms of Wilsonian RG flows and their possible relevance to construct composite Higgs models.
