Research output: Contribution to journalArticleResearchpeer-review


Quarks are always accompanied by glue. Neglecting this glue leads to infra-red divergences and indeed colour charges are only defined if we take the glue into account. Here we present a new method to derive the form of this gluonic distribution. Results for various configurations are reported. These gluonic dressings are then tested in a wide variety of explicit calculations: in every case we see that the Green's functions of the dressed particles possess a physical pole structure and that infra-red divergences are not present. Some conclusions are drawn.
