Dressed quark-gluon vertex form factors from gauge symmetry

Abstract

We present preliminary results on the longitudinal andand transverse form factors of the quark-gluon vertex as functions of the incoming and outgoing quark momenta and an angle θ=2π/3\theta =2\pi/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.
