Lattice study of the conformal window in QCD-like theories

We study the extent of the conformal window for an SU(3) gauge theory with N(f) Dirac fermions in the fundamental representation. We present lattice evidence for 12 <= N(f) <= 16 that the infrared behavior is governed by a fixed point, while confinement and chiral symmetry breaking are present for N(f) <= 8.
