Lattice Study of the Conformal Window in QCD-like Theories
Abstract
Using lattice simulations, we study the extent of the conformal window for an SU(3) gauge theory with Nf Dirac fermions in the fundamental representation. We present evidence that the infrared behavior is conformal for 12 ≤ Nf ≤ 16, governed by an infrared fixed point, while confinement and chiral symmetry breaking are present for Nf ≤ 8.
