Lattice Study of the Conformal Window in QCD-like Theories
arXiv:0712.0609 · doi:10.1103/PhysRevLett.100.171607
Abstract
Using lattice simulations, we study the extent of the conformal window for an $\text{SU}(3)$ gauge theory with $N_f$ Dirac fermions in the fundamental representation. We present evidence that the infrared behavior is conformal for $12 \leq N_f \leq 16$, governed by an infrared fixed point, while confinement and chiral symmetry breaking are present for $N_f \leq 8$.
