Quark gap equation with non-abelian Ball-Chiu vertex
A. C. Aguilar, J. C. Cardona, M. N. Ferreira +1
The full quark-gluon vertex is a crucial ingredient for the dynamical generation of a constituent quark mass from the standard quark gap equation, and its non-transverse part may b…
Non-Abelian Ball-Chiu vertex for arbitrary Euclidean momenta
A. C. Aguilar, J. C. Cardona, M. N. Ferreira +1
We determine the non-Abelian version of the four longitudinal form factors of the quark-gluon vertex, using exact expressions derived from the Slavnov-Taylor identity that this ver…
Nonperturbative results on the quark-gluon vertex
A. C. Aguilar, D. Binosi, J. C. Cardona +1
We present analytical and numerical results for the Dirac form factor of the quark-gluon vertex in the quark symmetric limit, where the incoming and outgoing quark momenta have the…
