`Strong-interaction physics from lattice QCD in Landau gauge'
Abstract: Lattice calculations of the Landau-gauge gluon and ghost propagators
have attracted quite some interest during the last 15 years.
Although lattice data for these elementary Green's functions of QCD is
of minor importance for a plain lattice-QCD based approach to QCD,
it is an important ingredient when one addresses QCD with functional methods.
In this talk I will review some of my recent lattice studies on this subject,
in particular those where there has been a valuable interplay between lattice
and functional studies in the past. I will also show how lattice data for
these propagators can be used to estimate the strong coupling constant
from first principles.
