# A study of the quark-gluon vertex

## TL;DR

This paper investigates the quark-gluon vertex function in quenched QCD using lattice simulations, providing initial results and outlining future plans for extracting the renormalised QCD coupling.

## Contribution

First lattice study of the quark-gluon vertex function in Landau gauge with O(a)-improved Wilson fermions at beta=6.0, including future renormalisation plans.

## Key findings

- Initial results for the vertex function in quenched QCD
- Discussion of momentum dependence and renormalisation prospects
- Plans for extracting the QCD coupling from the vertex

## Abstract

We present the first results from a study of the quark--gluon vertex function in the Landau gauge. The results are obtained for quenched QCD with an O(a)-improved Wilson fermion action, at beta=6.0. We discuss plans for further study, including extraction of a renormalised QCD coupling from the momentum dependence of the vertex.
