We study the gluon and ghost propagators of lattice Landau gauge in the
strong coupling limit β=0 in pure SU(2) lattice gauge theory to find
evidence of the conformal infrared behaviour of these propagators as predicted
by a variety of functional continuum methods for asymptotically small momenta
q2≪ΛQCD2. In the strong-coupling limit, this same
behaviour is obtained for the larger values of a2q2 (in units of the
lattice spacing a), where it is otherwise swamped by the gauge field
dynamics. Deviations for a2q2<1 are well parametrized by a transverse
gluon mass ∝1/a. Perhaps unexpectedly, these deviations are thus no
finite-volume effect but persist in the infinite-volume limit. They furthermore
depend on the definition of gauge fields on the lattice, while the asymptotic
conformal behaviour does not.Comment: 7 pages; talk presented at the XXVI International Symposium on
