Gluon coupling strength in HQCD with small cutoffs
Abstract
This contribution presents the running triple-gluon-vertex coupling constant, glambda, in Hamiltonians for the gluons that are characterized by the size 1/lambda. The coupling constant is obtained from renormalization group equations for effective particles in canonical light-front QCD in third order perturbation theory. lambda plays the role of a finite cutoff parameter and is varied from 100 Gev down to 100 MeV.
