We present preliminary results on the longitudinal and transverse form factors of the quark-gluon vertex as functions of the incoming and outgoing quark momenta and an angle θ = 2π/3 between them. The expressions for these form factors were previously derived from Slavnov-Taylor identities, gauge covariance and multiplicative renormalizability that firmly constrain the fermion-boson vertex.

Collective Perspective on Advances in Dyson—Schwinger Equation QCD
We survey contemporary studies of hadrons and strongly interacting quarks using QCD's Dyson—Schwinger equations, addressing the following aspects: confinement and dynamical chiral symmetry breaking;
Heavy-meson chiral Lagrangians, effective flavored couplings, SU(4) flavor breaking and their consequences
We review heavy quark flavor and spin symmetries, their exploitation in heavy meson effective theories and the flavored couplings of charmed and light mesons in the definition of their effective
The impact of transverse Slavnov-Taylor identities on dynamical chiral symmetry breaking
Abstract We extend earlier studies of transverse Ward-Fradkin-Green-Takahashi identities in QED, their usefulness to constrain the transverse fermion-boson vertex and their importance for

Distribution amplitudes of heavy mesons and quarkonia on the light front
The ladder kernel of the Bethe–Salpeter equation is amended by introducing a different flavor dependence of the dressing functions in the heavy-quark sector. Compared with earlier work this allows
The soft-gluon limit and the infrared enhancement of the quark-gluon vertex
The Schwinger–Dyson quark equation (SDE) combined with results from lattice simulation for the propagators are used to obtain information on the quark-gluon vertex, taking into account the recent
Analytic properties of the vertex function in gauge theories. I
The analytic properties of the vertex functions for massless scalar and massless and massive spinor electrodynamics are investigated. First, a general tensor form for the vertex consistent with the
Dynamical Model of Elementary Particles Based on an Analogy with Superconductivity. II
It is suggested that the nucleon mass arises largely as a self-energy of some primary fermion field through the same mechanism as the appearance of energy gap in the theory of superconductivity. The
Transverse Takahashi identities and their implications for gauge independent dynamical chiral symmetry breaking
In this article, we employ transverse Takahashi identities to impose valuable non-perturbative constraints on the transverse part of the fermion-photon vertex in terms of new form factors, the so
Interplay of dynamical and explicit chiral symmetry breaking effects on a quark
The relative contributions of explicit and dynamical chiral symmetry breaking in QCD models of the quark-gap equation are studied in dependence of frequently employed ans\"atze for the dressed
