Dyon condensation and colour confinement in dual QCD

Abstract

A dynamical model based on the magnetic symmetry of QCD vacuumhas been discussed to explore its magnetic response in dealingwith the confinement mechanism. The flux tube formulation of thedyonically condensed dual QCD vacuum is presented by computingthe asymptotic flux tube solutions of the field equations in thedynamically broken phase of the dual QCD vacuum which has beenshown to be responsible for the confinement of the colourelectric sources in the deep infrared regime. Deriving thegeneralised energy-momentum tensor, the energy and the quantizedangular momentum of the flux tube system have been computedanalytically, which provides a viable physical basis for theexplanation of the colour confinement in the non-perturbativeregime of QCD vacuum.
