Abstract

Using lattice simulations, we study the extent of the conformal window for an SU(3)\text{SU}(3) gauge theory with NfN_f Dirac fermions in the fundamental representation. We present evidence that the infrared behavior is conformal for 12Nf1612 \leq N_f \leq 16, governed by an infrared fixed point, while confinement and chiral symmetry breaking are present for Nf8N_f \leq 8.
