Resumen:
Within the refined Gribov-Zwanziger scenario for fourdimensional
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 adding a gluon
mass term to the usual Faddeev-Popov action yields one-loop
renormalization group improved gluon and ghost propagators which are in
reasonable 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. (C) 2022 Elsevier Inc.
