Abstract: (arXiv)
Most of the non-Abelian string-vortices studied so far are characterized by two-dimensional \cpn models with various degrees of supersymmetry on their world sheet. We generalize this construction to "composite" non-Abelian strings supporting the Grassmann G(L,M)\mathcal{G}(L,M) models (here L+M=NL+M=N). The generalization is straightforward and provides, among other results, a simple and transparent way for counting the number of vacua in N=(2,2){\mathcal N}=(2,2) Grassmannian model.
