Colour confinement as dual Meissner effect: $SU(2)$ gauge theory

Abstract

We demonstrate that confinement in $SU(2)$ gauge theory is produced by dual superconductivity of the vacuum. We show that for $T<T_c$ (temperature of deconfining phase transition) the $U(1)$ symmetry related to monopole charge conservation is spontaneously broken; for $T>T_c$ the symmetry is restored.
