摘要

The dyonic field-effective Lagrangian in the Abelian projection of quantum chromodynamics has been constructed using an Abelian Higgs model with confinement and dual superconductivity. It has been shown that Abelian dyons are formed by the non-Abelian dyons in the process of Abelianization. Euclidean space–time’s partition function has also been calculated using this approach. It has been further demonstrated that massive scalar mode controls the rate of condensation of the perturbation vacuum surrounding a colored source and other massive vector mode controls the colored flux’s penetration length, both for dyonically condensed vacuum state. The boundary condition between type I and type II superconductors is determined. Furthermore, it has been shown that superconductivity becomes the actual confinement method brought out by the dyonic condensation.
