Another look at the three-gluon vertex in the minimal Landau gauge

Abstract

The lattice three-gluon vertex in the Landau gauge is revisited using a large physical volume $\sim (8\text{fm}{)}^4$ and a large statistical ensemble. The improved calculation explores the symmetries of the hypercubic lattice to reduce the statistical uncertainties and addresses the evaluation of the lattice artefacts. Special attention is given to the low energy behaviour of the vertex and its relation to ghost dominance.
