Field, current, and charge distribution in a pure gauge SU(3) flux tube

The quark confinement in QCD is achieved by concentration of the chromoelectric field between quark-antiquark pair into a flux tube, which gives rise to linear potential. We study structure tube created static pure gauge SU(3) theory, using lattice Monte-Carlo simulations. calculate spatial distribution all three components and perform “zero curl subtraction” procedure obtain nonperturbative part longitudinal component field, we identify as responsible for formation tube. Taking derivatives obtained allows us extract electric charge magnetic current densities behavior these observables under smearing with respect continuum scaling investigated. Finally, briefly discuss role currents string tension.
