Higgs effect in consistent Kaluza-Klein models with branes [Elektronisk resurs]

• We continue consideration of models where the Higgs effect is produced by the presence of 3-brane fluctuating in compact extra dimensions. The consistent examples of such models may be obtained from previously known solutions of 6D supergravity. The low-energy limit for these models coincides with a version of Higgs model written in terms of gauge-invariant supercurrent variables. We also elaborate on vortices in the Abelian version of the theory and show how vortices that are singular from the 4D point of view become allowed due to higher-dimensional resolution of singularity.
