Abstract

We calculate the phase diagrams at high temperature of SU(N) gauge theories with massive fermions by minimizing the one-loop effective potential. Considering fermions in the adjoint (Adj) representation at various N we observe a variety of phases when N_f ≥ 2 Majorana flavours and periodic boundary conditions are applied to fermions. Also the confined phase is perturbatively accessible. For N = 3, we add Fundamental (F) representation fermions with antiperiodic boundary conditions to adjoint QCD to show how the Z (3)-symmetry breaks in the confined phase.
