Abstract

The scale-dependent renormalized coupling of SU(3) gauge theory coupled to Nf = 2 flavors of massless Dirac flavors in the sextet representation is presented in the range 0 < g2 < 6:5. This range includes the location where the βb-function turns zero in the MS scheme to 3-loop and 4-loop approximations, however our non-perturbative result shows a monotonically increasing β-function. Our lattice calclulations are carried out at several lattice spacings allowing for a controlled continuum extrapolation. We also comment on a recent similar calculation by Hasenfratz et al.
