Status of αs determinations from the non-perturbatively renormalised three-gluon vertex
Parrinello, C.; Richards, D. G.; Allés, B.; Panagopoulos, Haralambos G.; Pittori, C. (1998)We demonstrate the feasibility of computing α, from the lattice three-gluon vertex in the Landau gauge. Data from 164 and 244 quenched lattices at β = 6.0 are presented. Our main result is that 2-loop asymptotic scaling ...

αs from the non-perturbatively renormalised lattice three-gluon vertex
Allés, B.; Henty, D. S.; Panagopoulos, Haralambos G.; Parrinello, C.; Pittori, C.; Richards, D. G. (1997)We compute the running QCD coupling on the lattice by evaluating two-point and three-point off-shell gluon Green's functions in a fixed gauge and imposing non-perturbative renormalisation conditions on them. Our exploratory ...
