  Within the refined Gribov-Zwanziger scenario for four-dimensional Yang-Mills
theory in the Landau gauge, a gluon mass term is generated from the restriction
of the gauge field configurations to the first Gribov region. Tissier and
Wschebor have pointed out that simply adding a gluon mass term to the usual
Faddeev-Popov action yields one-loop renormalization group improved gluon and
ghost propagators which are in good agreement with the lattice data even in the
infrared regime. In this work, we extend their analysis to several alternative
renormalization schemes and show how the renormalization scheme dependence can
be used to achieve an almost perfect matching to the lattice data for the gluon
and ghost propagators.
