Dynamical chiral symmetry breaking and the fermion--gauge-boson vertex
read the original abstract
We present a workable model for the fermion-photon vertex, which is expressed solely in terms of functions that appear in the fermion propagator and independent of the angle between the relative momenta, and does not explicitly depend on the covariant-gauge parameter. It nevertheless produces a critical coupling for dynamical chiral symmetry breaking that is practically independent of the covariant-gauge parameter and an anomalous magnetic moment distribution for the dressed fermion that agrees in important respects with realistic numerical solutions of the inhomogeneous vector Bethe-Salpeter equation.

Radiative charmonium decays in a contact-interaction model with dynamical quark anomalous magnetic moment
Contact-interaction model with dynamical quark anomalous magnetic moment reproduces lattice QCD results for eta_c to gamma gamma and J/psi to gamma eta_c decays, consistent with 2026 data but not the 2024 measurement.
