Index Theorem for non-Supersymmetric Fermions Coupled to a non-Abelian String and Electric Charge Quantization
M. Shifman, A. Yung
Non-Abelian strings are considered in {\em non}-supersymmetric theories with fermions in various appropriate representations of the gauge group U(). We derive the electric charg…
Fradkin-Shenker Continuity and "Instead-of-Confinement" Phase
M. Shifman, A. Yung
In 1979 Fradkin and Shenker observed \cite{Frad} that if one considers a Yang-Mills theory fully Higgsed by virtue of scalar fields in the fundamental representation of the ${\rm S…
Critical Non-Abelian Vortex in Four Dimensions and Little String Theory
M. Shifman, A. Yung
As was shown recently, non-Abelian vortex strings supported in four-dimensional supersymmetric QCD with the U(2) gauge group and quark multiplets (flavors) bec…
Quantum Deformation of the Effective Theory on Non-Abelian string and 2D-4D correspondence
M. Shifman, A. Yung
We explore non-Abelian strings in the r=N-1 vacuum of N=2 supersymmetric QCD with the gauge group U(N) and N_f flavors of quarks (N_f\geq N), where r is the number of condensed qua…
Simple Models with Non-Abelian Moduli on Topological Defects
M. Shifman
I explain how conventional topological defects -- the Abrikosov-Nielsen-Olesen (ANO) string and domain walls -- can acquire non-Abelian moduli localized on their world sheets. The…
Understanding Confinement in QCD: Elements of a Big Picture
M. Shifman
I give a brief review of advances in the strong interaction theory. This talk was delivered at the Conference in honor of Murray Gell-Mann's 80th birthday, 24-26 February 2010, Sin…
