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 (3+1)-dimensional N = 2 SQCD with SU(2) gauge group and Nf = 2 flavors of fundamental hypermultiplets (quarks). This theory is perturbed by a small mass term of(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 non-Abelian strings is the occurrence of orientational moduli associated with the possibility of rotations of their color fluxes inside a global SU(N) group.(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, " non-Abelian " strings and various junctions. Our main but not exclusive task is the study of localization of non-Abelian gauge fields on the walls. The model(More)
We continue explorations of non-Abelian strings, focusing on the solution of a heterotic deformation of the CP (N − 1) model with an extra right-handed fermion field and N = (0, 2) supersymmetry. This model emerges as a lowenergy theory on the worldsheet of the BPS-saturated flux tubes (strings) in N = 2 supersymmetric QCD deformed by a superpotential of a(More)
We consider non-Abelian BPS-saturated flux tubes (strings) inN = 2 supersymmetric QCD deformed by superpotential terms of a special type breaking N = 2 supersymmetry down to N = 1 . Previously it was believed that worldsheet supersymmetry is “accidentally” enhanced due to the facts that N = (1, 1) SUSY is automatically elevated up to N = (2, 2) on CP (N −(More)
We study the confinement scenario in N=2 supersymmetric SU(2) gauge theory near the monopole point upon breaking of N=2 supersymmetry by the adjoint matter mass term. We confirm claims made previously that the Abrikosov–Nielsen–Olesen string near the monopole point fails to be a BPS state once next-to-leading corrections in the adjoint mass parameter taken(More)
