abstract = {Front-Form Hamiltonian dynamics provides a framework in which QCD’s vacuum is simple and
states are boost invariant. However, canonical expressions are divergent and must be regulated in order to
establish well-defined eigenvalue problems. The Renormalization Group Procedure for Effective Particles
(RGPEP) provides a systematic way of finding counterterms and obtaining regulated Hamiltonians. Among its
achievements is the description of asymptotic freedom, with a running coupling constant defined as the coefficient
in front of the three gluon-vertex operators in the regulated Hamiltonian. However, the obtained results need a
deeper understanding, since the coupling exhibits a finite dependence on the regularization functions, at least
at the third-order term in the perturbative expansion. Here we present a similar derivation using a different
regularization scheme based on massive gluons. The procedure can be extended to incorporate contributions
from virtual fermions.},
