Description
We present a Schwinger-Dyson analysis of the three- and four-gluon vertices in the soft-kinematic configuration, where one external momentum vanishes. The key assumption in our analysis is the validity of a ''planar degeneracy'', which states that the leading form factor for each vertex is well described by a single Bose-symmetric variable defining a plane in momentum space. We find that this property leads to significant simplification of the underlying equations and can be verified numerically to a high degree of accuracy. The results obtained with this approach capture the leading non-perturbative features of both vertices and are in good agreement with current lattice simulations.
