Status of alpha_s determinations from the non-perturbatively renormalised three-gluon vertex

Abstract

We demonstrate the feasibility of computing alpha_s from the lattice three-gluon vertex in the Landau gauge. Data from 16^4 and 24^4 quenched lattices at beta=6.0 are presented. Our main result is that 2-loop asymptotic scaling is observed for momenta in the range 1.8-2.3 Gev, where lattice artifacts appear to be under control.
