Dissecting the string theory dual of QCD

Input from QCD and string theory is used in order to elucidate basic features of the string theory dual of QCD, It is argued that the relevant string theory is a five-dimensional version of the type-0 superstring. The vacuum solution is asymptotically AdS5, and the geometry near the boundary is stringy. The structure of YM perturbation theory however emerges near the boundary. In the IR, the th...

QCD String as Vortex String in Seiberg-Dual Theory

We construct a classical vortex string solution in a Seiberg-dual theory of N = 1 supersymmetric SO(Nc) QCD which flows to a confining phase. We claim that this vortex string is a QCD string, as previouly argued by M. Strassler. In SO(Nc) QCD, it is known that stable QCD strings exist even in the presence of dynamical quarks. We show that our vortex strings are stable in the Seiberg-dual theory.

Remarks on string solitons

We consider generalized self-duality equations for U(2r) Yang-Mills theory on R8 with quaternionic structure. We employ the extended ADHMmethod in eight dimensions to construct exact soliton solutions of the low-energy effective theory of the heterotic string.

String breaking in QCD: dual superconductor vs. stochastic vacuum model

Abstract: Effects of dispersion of the chromoelectric field of the flux tube on the stringbreaking distance are studied. The leading-order correction is shown to slightly diminish the result following from the Schwinger formula. Instead, accounting for corrections of all orders might result, at certain values of the Landau-Ginzburg parameter, in an increase of the string-breaking distance up to...

From Qcd to Dual Superconductivity to Effective String Theory

We show how an effective field theory of long distance QCD, describing a dual superconductor, can be expressed as an effective string theory of superconducting vortices. We use the semiclassical expansion of this effective string theory about a classical rotating string solution in any spacetime dimension D to obtain the semiclassical meson energy spectrum. We argue that the experimental data o...
