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…
Worldsheets in Holography: Computing Corrections to the Veneziano Amplitude
Edwin Ireson
We provide a brief summary of a method to calculate improvements to the Veneziano Amplitude, creating sub-leading non-linearities in the Regge trajectory of states. We formulate it…
Supersymmetrising the GSY Soliton
Edwin Ireson, Mikhail Shifman, Alexei Yung
We supersymmetrise the Hopfion studied in a previous work. This soliton represents a closed semilocal vortex string in gauge theory. It carries nonzero Hopf number due to th…
Equivalence of Meson Scattering Amplitudes in Strong Coupling Lattice and Flat Space String Theory
Adi Armoni, Edwin Ireson, Davide Vadacchino
We consider meson scattering in the framework of the lattice strong coupling expansion. In particular we derive an expression for the 4-point function of meson operators in the pla…
