Historical curiosity: how asymptotic freedom of the Yang-Mills theory could have been discovered three times before Gross, Wilczek, and Politzer, but was not
M. Shifman
This article was published in 2001 in Festschrift "At the Frontier of Particle Physics; Handbook of QCD", Ed. M. Shifman, (World Scientific, Singapore, 2001), Vol. 1, page 126. Asy…
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…
