TL;DR

This paper studies the properties of QCD flux tubes for various SU(3) representations using lattice QCD, providing insights into confinement mechanisms and the flux tubes used in models of heavy ion collisions.

Contribution

It presents the first detailed lattice QCD calculations of flux tube properties for multiple SU(3) representations, including field densities, Casimir scaling, and widths.

Findings

Flux tube properties follow Casimir scaling.

Widths of flux tubes are computed for different representations.

Results enhance understanding of confinement and heavy ion collision models.

Abstract

We investigate the QCD flux tubes linking static colour charges of different SU(3) representations, relevant to the understanding of confinement and of the Lund strings of Heavy Ion Collisions. The colour field densities, the Casimir scaling factors and the widths for the flux tubes of the first five different representations are computed in quenched SU(3) lattice QCD. This study is relevant to understand the mechanisms of confinement and also the flux tubes utilized in the Lund Model and in other models of Heavy Ion Collisions.
