Query: Exploring the infrared Landau gauge propagators using large asymmetric
  lattices   We report on the infrared limit of the quenched lattice Landau gauge gluon
and ghost propagators computed from large asymmetric lattices. In particular,
the compatibility of the pure power law infrared solutions of the
Dyson-Schwinger equations with the lattice data is investigated and the
exponent $\kappa$ is measured. The gluon lattice data favour $\kappa \sim
0.52$, which would imply a vanishing zero momentum gluon propagator. For the
subset of lattices where the ghost propagator was computed, the data is not
compatible with a pure power law. Our data also show a decreasing running
coupling in the infrared region. Furthermore, positivity violation for the
gluon propagator is also verified.
