Description
We report novel lattice QCD results for the position-space gluon propagator from quenched lattice-QCD simulations. Using standard Wilson action, we have computed the gluon propagator in position space with a detailed treatment of discretization errors.
We discuss on the usefulness of the long-distance behavior of gluon propagator for constraining the deep infrared running of the gluon propagator.
In addition, we will show results for the three-gluon vertex that support the
gluon-mass generation mechanism based in the existence of massless poles, longitudinaly coupled to the gluon momenta, in the vertices of QCD.
