Domain walls in supersymmetric QCD: from weak to strong coupling
نویسندگان
چکیده
We consider domain walls that appear in supersymmetric QCD with Nf , Nc massive flavors. In particular, for 2Nf , Nc we explicitly construct the domain walls that interpolate between vacua labeled by i and i 1 Nf . We show that these solutions are Bogomol’nyi-Prasad-Sommerfield saturated for any value of the mass of the matter fields. This fact allows us to evaluate the large mass limit of these domain walls. We comment on the relevance of these solutions for supersymmetric gluodynamics.

Relation between S-duality in N=2 SQCD and Non-Abelian Duality in N=1 SQCD
With the help of M-theory configuration of N=1 supersymmetric QCD, we analyze the strong coupling moduli of N=1 theory and its relation with S-duality transformation in N=2 supersymmetric QCD. As a result we confirm that two type-IIA descriptions for N=1 supersymmetric QCD, one of them being strong coupling description and another being weak, correspond to a single M-theory description for N=1 ...
متن کاملComplex BPS Domain Walls and Phase Transition in Mass in Supersymmetric QCD A. Smilga and A. Veselov
We study the domain walls connecting different chirally asymmetric vacua in supersymmetric QCD. We show that BPS – saturated solutions exist only in the limited range of mass m ≤ m∗ ≈ 0.8| < Tr λ2 > |1/3. When m > m∗, the domain wall either ceases to be BPS – saturated or disappears altogether. In any case, the properties of the system are qualitatively changed.

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 we work with is N = 2 QCD, with the gau...

متن کاملDomain Walls in Large N Supersymmetric QCD
We explicitly construct BPS domain walls interpolating between neighboring chirally asymmetric vacua in the large N limit of pure supersymmetric QCD. The BPS equations for the corresponding ZN symmetric order parameter effective Lagrangian reduce to those in the AN Landau-Ginsburg model assuming that the higher derivative terms in the Kähler potential are suppressed in the large N limit. These ...
