Dynamical breaking of magnetic symmetry in dual version of QCD and SUSY QCD

The geometrical structure of the local non-Abelian gauge theory has been an alysed in terms of the magnetic symmetry. Based on it, the mathematical fou ndation of dual QCD in fibre bundle form has been discussed mainly to analy se the confinement mechanism of QCD vacuum. The dynamical breaking of magne tic symmetry leading to the magnetic condensation (dual superconductivity) of QCD vacuum has been shown to push the system in confined phase. The flux tube structure of dual QCD vacuum has been analysed by computing the asymp totic string solutions of the field equations and the string energy has bee n computed which resembles with the Abrikosov vortex in the type-II superco nductor. Supersymmetrising the dual QCD version for the case of N=1 Supersy mmetry, the topological structure of supersymmetric dual QCD (SDQCD) has be en investigated and the effect of the dynamical breaking of magnetic symmet ry in terms of the probable state of Supersymmetric dual Superconductivity in SDQCD vacuum is analysed.
