Query: The dynamical origin of the refinement of the Gribov-Zwanziger theory   In recent years, the Gribov-Zwanziger action was refined by taking into
account certain dimension 2 condensates. In this fashion, one succeeded in
bringing the gluon and the ghost propagator obtained from the GZ model in
qualitative and quantitative agreement with the lattice data. In this paper, we
shall elaborate further on this aspect. First, we shall show that more
dimension 2 condensates can be taken into account than considered so far and,
in addition, we shall give firm evidence that these condensates are in fact
present by discussing the effective potential. It follows thus that the
Gribov-Zwanziger action dynamically transforms itself into the refined version,
thereby showing that the continuum nonperturbative Landau gauge fixing, as
implemented by the Gribov-Zwanziger approach, is consistent with lattice
simulations.
