Description
The renormalization group beta function describes the running of the renormalized coupling, connects the ultraviolet and infrared regimes of quantum field theories, and characterizes the nature of gauge-fermion systems. Using the concept of the continuous beta function and renormalized couplings obtained from the gradient flow, we present results for SU(3) gauge theories with $N_f=2$, 4, 6, 8, 10 or 12 fundamental flavors. Our results are based on dynamical gauge field ensembles generated with three times stout-smeared Möbius domain-wall fermions and Symanzik gauge action.
