On Asymptotic Safety in the Litim–Sannino Model

Abstract

In the \({\text{SU}}({{N}_{c}})\) gauge theory with \({{N}_{f}}\) color quarks and \(N_{f}^{2}\) colorless complex scalars, an expression for the nontrivial ultraviolet fixed point is obtained as an expansion in the Veneziano parameter up to the third order. The fixed point has a one-dimensional UV critical surface and perturbatively implements the asymptotic safety scenario. The conformal window and the spectrum of anomalous dimensions of different operators are discussed.
