General Composite Non-Abelian Strings and Flag Manifold Sigma Models
Edwin Ireson
We fully investigate the symmetry breaking patterns occurring upon creation of composite non-Abelian strings: vortex strings in non-Abelian theories where different sets of colours…

Composite Non-Abelian Strings with Grassmannian Models on the World Sheet
Edwin Ireson, Mikhail Shifman, Alexei Yung
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 th…

Heterotically Deformed Sigma Models on the World Sheet of Semilocal Strings in SQED
Edwin Ireson, Mikhail Shifman, Alexei Yung
A new two dimensional Supersymmetric Non-Linear Sigma Model describes the dynamics of internal moduli of the BPS semi-local vortex string supported in four dime…
