Query: Running alpha(s) from Landau-gauge gluon and ghost correlations   We estimate the running coupling constant of the strong interactions within
the nonperturbative framework of lattice QCD in Landau gauge. Our calculation
is based on the ghost-gluon vertex which in the particular case of Landau gauge
allows for a definition of alpha(s) in a MOM scheme solely in terms of the
gluon and ghost dressing functions. As a first step we investigate the zero and
two-flavour case and report here on preliminary results.
