Unified description of color-electric and color-magnetic strings in hybrid vacua of supersymmetric QCD
E. Ievlev, D. Vasilev, A. Yung
We study non-Abelian strings supported in -vacua of 4D supersymmetric QCD (SQCD) with gauge group and quark hypermultiplets (), where $r<N…
Hadrons in supersymmetric QCD from non-Abelian string on 2D black hole
E. Ievlev, A. Marshakov, G. Sumbatian +1
We continue the study of non-Abelian vortex string in 4D supersymmetric QCD as critical superstring, and extend this analysis to gauge theory with arbitrary…
Degenerate vortices and world-line instantons in three-dimensional gauge theories
Evgenii Ievlev, Mikhail Shifman
In this paper we continue the study of particle-like topological solitons with degenerate masses and their mixing due to world-line instantons. Previously, this phenomenon was stud…
Degenerate kinks and kink-instantons in two-dimensional scalar field models with and supersymmetry
Evgenii Ievlev, Mikhail Shifman
Models with classically degenerate vacua often support quasiclassical configurations of nontrivial topology. In (0+1)-dimensional quantum mechanics with a double-well potential, fo…
Degenerate Domain Walls in Supersymmetric Theories
Shi Chen, Evgenii Ievlev, Mikhail Shifman
In supersymmetric Yang-Mills theories (SYM) tension-degenerate domain walls are typical. Adding matter fields in fundamental representation we arrive at supersymmetric QCD (SQCD) s…
Search for NS 3-form Flux Induced Vacua for the Critical Non-Abelian Vortex String
E. Ievlev, P. Pichugina, A. Yung
It has been demonstrated that the non-Abelian solitonic vortex string in four-dimensional (4D) supersymmetric QCD (SQCD) with gauge group U(2) and quark hyp…
