Title: Studying the infrared behaviour of gluon and ghost propagators using large asymmetric lattices

Abstract

We report on the infrared limit of the quenched lattice Landau gauge gluon propagator computed from large asymmetric lattices. In particular, the compatibility of the pure power law infrared solution (q2)2{kappa} of the Dyson-Schwinger equations is investigated and the exponent {kappa} is measured. Some results for the ghost propagator and for the running coupling constant will also be shown.
