We compute the Standard Model scalar coupling (lambda) evolution in a particular QCD resummation scheme, where the QCD coupling becomes infrared finite due to the presence of a dynamically generated gluon mass, leading to the existence of a non-perturbative infrared fixed point. We discuss how this scheme can be fixed taking recourse to phenomenological considerations in the infrared region. The QCD beta function associated to this non-perturbative coupling when introduced into the SM renormalization group equations increases the lambda values at high energies. (C) 2015 The Authors.
