Abstract
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.
