One-loop unquenched three-gluon and ghost-gluon vertex in the Curci-Ferrari model
Abstract
In this article we study the unquenched three-gluon and ghost-gluon vertex in all momentum range going from the ultraviolet to the infrared regime using the Curci-Ferrari model at one-loop in Landau gauge as an extension of the results presented in Pelaez:2013cpa. Results are compared with recent lattice data for SU(3) in the unquenched case. This calculation is a pure prediction of the model because it does not require fixing any parameter once two-point functions are fitted. An analysis of the influence of dynamical quarks in the position of the zero crossing of the three-gluon vertex is presented. Due to the recent improvements in infrared lattice data for the quenched three-gluon correlation function Aguilar:2021lke we also redo the comparison between our one-loop results in this limit and the lattice obtaining a very good match.
