Description
We investigate Landau gauge $SU(3)$ Yang-Mills theory in a
systematic vertex expansion scheme for the effective action with
the functional renormalisation group.
Particular focus is put on the dynamical creation of the gluon mass
gap at non-perturbative momenta and the consistent treatment of
quadratic divergences. The non-perturbative ghost and transverse
gluon propagators as well as the momentum-dependent ghost-gluon,
three-gluon and four-gluon vertices are calculated self-consistently
with the classical action as only input. The apparent convergence of
the expansion scheme is discussed and within the errors, our
numerical results are in quantitative agreement with available
lattice results.
