N=1 Duality in the Chiral Limit from N=2 Duality
M. Shifman, A. Yung
We study a deformation of N=2 supersymmetric QCD with U(N) gauge group and N_f quark flavors induced by the mass term μfor the adjoint matter which breaks supersymmetry down to N=1…
More on the Abrikosov Strings with Non-Abelian Moduli
M. Shifman, Gianni Tallarita, A. Yung
We continue explorations of deformed Abrikosov-Nielsen-Olesen (ANO) strings, with non-Abelian moduli on the world sheet. In a simple model with an extra field we find classically s…
Non-Abelian Duality and Confinement in N=2 Supersymmetric QCD
M. Shifman, A. Yung
In N=2 supersymmetric QCD with the U(N) gauge group and N_f>N we study the crossover transition from the weak coupling regime at large ξto strong coupling at small ξwhere ξis the F…
Multiflavor QCD* on R_3 x S_1: Studying Transition From Abelian to Non-Abelian Confinement
M. Shifman, M. Unsal
The center-stabilized multiflavor QCD* theories formulated on R_3 x S_1 exhibit both Abelian and non-Abelian confinement as a function of the S_1 radius, similar to the Seiberg-Wit…
Confinement in Yang--Mills: Elements of a Big Picture
M. Shifman, M. Unsal
We present a nontechnical review of the current understanding of the phenomenon of color confinement. The emphasis is put on recent advances. This is a combined and slightly expand…
Non-Abelian Strings and the Luscher Term
M. Shifman, A. Yung
We calculate the Luscher term for recently suggested non-Abelian flux tubes (strings). The main feature of the non-Abelian strings is the presence of orientational zero modes assoc…
Non-Abelian Semilocal Strings in N=2 Supersymmetric QCD
M. Shifman, A. Yung
We consider a benchmark bulk theory in four-dimensions: N=2 supersymmetric QCD with the gauge group U(N) and N_f flavors of fundamental matter hypermultiplets (quarks). The nature…
Non-Abelian Meissner Effect in Yang--Mills Theories at Weak Coupling
A. Gorsky, M. Shifman, A. Yung
We present a weak-coupling Yang--Mills model supporting non-Abelian magnetic flux tubes and non-Abelian confined magnetic monopoles. In the dual description the magnetic flux tubes…
Non-Abelian String Junctions as Confined Monopoles
M. Shifman, A. Yung
Various dynamical regimes associated with confined monopoles in the Higgs phase of N=2 two-flavor QCD are studied. The microscopic model we deal with has the SU(2)xU(1) gauge group…
Localization of Non-Abelian Gauge Fields on Domain Walls at Weak Coupling (D-brane Prototypes)
M. Shifman, A. Yung
Building on our previous results, we study D-brane/string prototypes in weakly coupled (3+1)-dimensional supersymmetric field theory engineered to support (2+1)-dimensional domain…
