The lattice infrared Landau gauge gluon propagator: from finite volume to the infinite volume

Understand

The Landau gauge lattice gluon propagator is discussed for different sets of lattices.

• Particular attention is given to its infrared properties.
• Our results show that the lattice propagator can be made compatible with either the decoupling-like or the scaling-like solution of the Dyson-Schwinger equations.
• Furthermore, the analysis of the Cucchieri-Mendes bounds is performed onsidering large volume simulations and the Oliveira-Silva ratios are computed.
