Nonperturbative β function of twelve-flavor SU(3) gauge theory
Abstract We study the discrete β function of SU(3) gauge theory with N f = 12 massless fermions in the fundamental representation. Using an nHYP-smeared staggered lattice action and an improved gradient flow running coupling g˜c2L $$ {\tilde{g}}_c^2(L) $$ we determine the continuum-extrapolated disc...
