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 are prototypes of… (More)

We study nonabelian vortices (flux tubes) in SU(N) gauge theories, which are responsible for the confinement of (nonabelian) magnetic monopoles. In particular a detailed analysis is given of N = 2… (More)

We consider a benchmark bulk theory in four-dimensions: N = 2 supersymmetric QCD with the gauge group U(N) and Nf flavors of fundamental matter hypermultiplets (quarks). The nature of the BPS strings… (More)

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)×U(1) gauge group, with a… (More)

This paper could have been entitled “D branes and strings from flesh and blood.” We study field theoretic prototypes of D branes/strings. To this end we consider (2+1)-dimensional domain walls in… (More)

We consider non-Abelian 1/2 BPS flux tubes (strings) in a deformed N = 2 supersymmetric gauge theory, with mass terms μ1,2 of the adjoint fields breaking N = 2 down to N = 1. The main feature of the… (More)

We consider non-Abelian BPS-saturated flux tubes (strings) in N = 2 super-symmetric QCD deformed by superpotential terms of a special type breaking N = 2 supersymmetry down to N = 1. Previously it… (More)

The N=2 supersymmetric gauge theory with gauge group SU(2) is considered. The instanton field is calculated explicitly using the superfield formalism. The instanton-induced effects are encoded in the… (More)

Building on our previous results (Ref. [4]), we study D-brane/string prototypes in weakly coupled (3+1)-dimensional supersymmetric field theory engineered to support (2+1)-dimensional domain walls, "… (More)

In the last decade it became clear that methods and techniques based on supersymmetry provide deep insights in quantum chromodynamics and other supersymmetric and non-supersymmetric gauge theories at… (More)
