Abstract

The quark-gluon vertex is an important object of QCD, the theory describing the strong interaction between quarks and gluons. Studies have shown that this quantity is relevant for the dynamical chiral symmetry breaking pattern in the vacuum. The goal of this project is to obtain the quark-gluon vertex at finite temperature around the deconfinement/chiral transition using the tools provided by lattice QCD, a very successful framework for non-perturbative studies of quantum field theories. It will be the first time that the quark-gluon vertex at finite temperature is determined using lattice QCD. The propagators, which are a by-product of this project, are also of interest in themselves. (AU)
