Abstract

The computation of the four-gluon and ghost-gluon vertices in the Landau gauge using high statistical lattice ensembles for 32⁴ and 48⁴ volumes is addressed. For the four-gluon vertex, our previous results for the collinear kinematics are updated allowing to get a better coverage of the IR region. Furthermore, the one-particle irreducible ghost-gluon Green function in the soft gluon limit is computed covering, with precision, a large momentum region.
