Description
By means of Numerical Stochastic Perturbation Theory (NSPT), we investigate the lattice gluon propagator up to the third loop in the limit of infinite volume and at vanishing lattice spacing.
Based on known anomalous dimensions and a parametrization of both the
hypercubic symmetry group H(4) and finite-size effects, we calculate the
non-logarithmic contributions iteratively starting with the first-loop expression.
