Figure 1

Phase diagram for theories with fermions in the: (i) fundamental representation, (ii) two-index antisymmetric, (iii) two-index symmetric, (iv) adjoint representation as a function of the number of flavors and the number of colors. The shaded areas depict the corresponding conformal windows. The upper solid curve represents the loss of asymptotic freedom, the lower curve the loss of chiral symmetry breaking. The dashed curves show the existence of a Banks-Zaks fixed point. Picture taken from 2.Reuse & Permissions
