Get PDFWe consider the gluon propagator D(p2) at various lattice sizes and
spacings in the case of pure SU(3) Yang-Mills gauge theories using the Landau
gauge fixing. We discuss a class of fits in the infrared region in order to
(in)validate the tree level analytical prediction in terms of the (Refined)
Gribov-Zwanziger framework. It turns out that an important role is played by
the presence of the widely studied dimension two gluon condensate
⟨A2⟩. Including this effect allows to obtain an acceptable fit up to
1 \'{a} 1.5 GeV, while corroborating the Refined Gribov-Zwanziger prediction
for the gluon propagator. We also discuss the infinite volume extrapolation,
leading to the estimate D(0)=8.3±0.5GeV−2. As a byproduct, we can
also provide the prediction ⟨g2A2⟩≈3GeV2 obtained at
the renormalization scale μ=10GeV.Comment: 17 pages, 10 figures, updated version, accepted for publication in
