Descrição
On this talk we report on the computation of the four gluon and of the ghost-gluon one-particle irreducible Green functions using lattice QCD simulations performed in the Landau gauge and for pure Yang-Mills SU(3) theory. For the four gluon vertex an update of our previous calculation combining 32^4 and 48^4 results is given for the three form factors published. For the ghost-gluon vertex we report our preliminary results for the soft-gluon limit (zero gluon momentum) using a subset of the ensembles generated to study the four gluon vertex.
