Abstract

In a class of non-Abelian solitonic vortex strings supported in certain N = 2 super-Yang–Mills theories we search for the vortex which can behave as a critical fundamental string. We use the Polchinski–Strominger criterion of the ultraviolet completeness. We identify an appropriate four-dimensional bulk theory: it has the U(2) gauge group, the Fayet–Iliopoulos term and four flavor hypermultiplets. It supports semilocal vortices with the world-sheet theory for orientational (size) moduli described by the weighted CP(2,2) model. The latter is superconformal. Its target space is six-dimensional. The overall Virasoro central charge is critical. Lastly, we show that the world-sheet theory on the vortex supported in this bulk model is the bona fide critical string.

Non-Abelian semilocal strings in N=2 supersymmetric QCD

Journal Article Shifman, M ; Yung, A ; Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg 188300 ; ... - Physical Review. D, Particles Fields

We consider a benchmark bulk theory in four dimensions: N=2 supersymmetric QCD with the gauge group U(N) and N{sub f} flavors of fundamental matter hypermultiplets (quarks). The nature of the Bogomol'nyi-Prasad-Sommerfield (BPS) strings in this benchmark theory crucially depends on N{sub f}. If N{sub f}{>=}N and all quark masses are equal, it supports non-Abelian BPS strings which have internal (orientational) moduli. If N{sub f}>N these strings become semilocal, developing additional moduli {rho} related to (unlimited) variations of their transverse size. Using the U(2) gauge group with N{sub f}=3, 4 as an example, we derive an effective low-energy theory on themore »« less

Studying critical string emerging from non-Abelian vortex in four dimensions

Journal Article Koroteev, P. ; Shifman, M. ; Yung, A. - Physics Letters B

Recently a special vortex string was found in a class of soliton vortices supported in four-dimensional Yang–Mills theories that under certain conditions can become infinitely thin and can be interpreted as a critical ten-dimensional string. The appropriate bulk Yang–Mills theory has the U(2) gauge group and the Fayet–Iliopoulos term. It supports semilocal non-Abelian vortices with the world-sheet theory for orientational and size moduli described by the weighted CP(2,2) model. Here, the full target space ismore »« less

Non-Abelian confinement in N=2 supersymmetric QCD: Duality and kinks on confining strings

Journal Article Shifman, M ; Yung, A ; Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg 188300 - Physical Review. D, Particles Fields

Recently we observed a crossover transition (in the Fayet-Iliopoulos parameter) from weak to strong coupling in N=2 supersymmetric QCD with the U(N) gauge group and N{sub f}>N quark flavors. At strong coupling this theory can be described by a dual non-Abelian weakly coupled supersymmetric QCD with the dual gauge group U(N{sub f}-N) and N{sub f} light dyon flavors. Both theories support non-Abelian strings. We continue the study of confinement dynamics in these theories, in particular, metamorphoses of excitation spectra, from a different side. A number of results obtained previously are explained, enhanced and supplemented by analyzing the world-sheet dynamics onmore »« less

Non-Abelian duality and confinement in N=2 supersymmetric QCD

Journal Article Shifman, M ; Yung, A ; Petersburg Nuclear Physics Institute, Gatchina, St. Petersburg 188300 - Physical Review. D, Particles Fields

In N=2 supersymmetric QCD with the U(N) gauge group and N{sub f}>N we study the crossover transition from the weak coupling regime at large {xi} to strong coupling at small {xi}, where {xi} is the Fayet-Iliopoulos parameter. We find that at strong coupling a dual non-Abelian weakly coupled N=2 theory exists, which describes low-energy physics at small {xi}. The dual gauge group is U(N{sub f}-N), and the dual theory has N{sub f} flavors of light dyons, to be compared with N{sub f} quarks in the originalU(N) theory. Both, the original and dual theories are Higgsed and share the same globalmore »« less

Higher winding strings and confined monopoles in N=2 supersymmetric QCD

Journal Article Auzzi, R ; Bolognesi, S ; Shifman, M - Physical Review. D, Particles Fields

We consider composite string solutions in N=2 SQCD with the gauge group U(N), the Fayet-Iliopoulos term {xi}{ne}0 and N (s)quark flavors. These bulk theories support non-Abelian strings and confined monopoles identified with kinks in the two-dimensional world-sheet theory. Similar and more complicated kinks (corresponding to composite confined monopoles) must exist in the world-sheet theories on composite strings. In a bid to detect them we analyze the Hanany-Tong (HT) model, focusing on a particular example of N=2. Unequal quark mass terms in the bulk theory result in the twisted masses in the N=(2,2) HT model. For spatially coinciding 2-strings, we findmore »« less
