Monopoles without magnetic charges: Finite energy monopole–antimonopole configurations in CP1 model and restricted QCD

Abstract

We propose a new type of regular monopole-like field configuration in quantum chromodynamics (QCD) and CP 1 model. The monopole configuration can be treated as a monopoleantimonopole pair without localized magnetic charges. An exact numeric solution for a simple monopole-antimonopole solution has been obtained in CP 1 model with an appropriate potential term. We suppose that similar monopole solutions may exist in effective theories of QCD and in the electroweak standard model.
