Bosonic fields in the stringlike defect model

We study localization of bosonic bulk fields on a stringlike defect with codimension 2 in a general space time dimension in detail. We show that in cases of spin-0 scalar and spin-1 vector fields there are an infinite number of massless Kaluza-Klein states which are degenerate with respect to the radial quantum number, but only the massless zero-mode state among them is coupled to the fermion on the stringlike defect. We also comment on interesting extensions of the model at hand to various directions such as little superstring theory, conformal field theory, and a supersymmetric construction.
