Description
In the present work we determine the transversely-projected quark-gluon vertex in the context of unquenched QCD with two degenerate light dynamical quarks in the Landau gauge. This is accomplished by solving the Schwinger-Dyson equation within the 3PI effective action formalism, employing lattice data for the gluon and quark propagators, and the three-gluon vertex. Our findings reveal that the classical form factor displays a significant angular dependence, and is in excellent agreement with recent lattice data in the soft-gluon configuration. The remaining form factors are computed through a single integration, confirming a clear hierarchy, in agreement with previous results.
