Nonperturbative Renormalization of Operators in Near-Conformal Systems Using Gradient Flows

We propose a continuous real space renormalization group transformation based on gradient flow, allowing for a numerical study of renormalization without the need for costly ensemble matching. We apply our technique in a pilot study of SU$(3)$ gauge …

Lattice study of the conformal window in QCD-like theories

Using lattice simulations, we study the extent of the conformal window for an $textSU(3)$ gauge theory with $N_f$ Dirac fermions in the fundamental representation. We present evidence that the infrared behavior is conformal for $12 leq N_f leq 16$, …
