Abstract

This is the second of two papers devoted to the perturbative computation of the ghost and gluon propagators in SU(3)SU(3) Lattice Gauge Theory. Such a computation should enable a comparison with results from lattice simulations in order to reveal the genuinely non-perturbative content of the latter. The gluon propagator is computed by means of Numerical Stochastic Perturbation Theory: results range from two up to four loops, depending on the different lattice sizes. The non-logarithmic constants for one, two and three loops are extrapolated to the lattice spacing a→0a→0 continuum and infinite volume V→∞V→∞ limits.
