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 $(q^2)^{2kappa}$ 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.
