Dual QCD formulation and quark-antiquark static potential

Abstract

In order to explore the low energy behavior and the non-trivial dynamics of QCD, a dual gauge theory of QCD has been studied using its magnetic symmetry propertieswhich takes into account not only the local structure but also the topological structure of a non-Abelian gauge symmetry into dynamics. As a result, the dynamical structure of the resulting dual QCD formulation and its flux tube structure have been investigated and the static inter-quark potential using the gluon propagator has been computed analytically that has been shown to have the linear and the Yukawa part which has been shown to reasonably fit with the corresponding phenomenological potential. The graphical representation clearly shows the dominance of the linear confinement over large hadronic distances in infrared regime of QCD and indicates towards the permanent confinement of the colored quarks inside the hadrons in the magnetically condensed QCD vacuum.
