dc.descriptionWe 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 $(q^2)^{2κ}$ of the Dyson-Schwinger equations is investigated and the exponent $κ$ is measured. The lattice data favours $κ\sim 0.52$, which would imply a vanishing zero momentum gluon propagator as predicted by the Kugo-Ojima confinement mechanism and the Zwanziger horizon condition. Results for the ghost propagator and for the running coupling constant are shown.
