Abstract
We summarize the higher-loop perturbative computation of the ghost and gluon propagators in SU(3) Lattice
Gauge Theory. Our final aim is to compare with results from lattice simulations in order to expose the genuinely nonperturbative
content of the latter. By means of Numerical Stochastic Perturbation Theory we compute the ghost and gluon
propagators in Landau gauge up to three and four loops. We present results in the infinite volume and a→0 limits, based on
a general fitting strategy.
