Dual Higgs model with dual Dirac strings Original Research Article

We investigate a dual Higgs model with dual Dirac strings invariant under U(1) gauge transformations, where U(1) is the Abelian gauge group of dual-vector potential transformations spontaneously broken by the Higgs mechanism. The action of a dual Dirac string calculated in leading order in the large Higgs field mass expansion coincides with a dual version of that obtained by Nambu. For the example of the string tension at the classical tree-level approach we develop a procedure for the computation of contributions of string-string interactions. Non-perturbative phenomena of compact QED are discussed.
