Supersymmetric Intersecting Domain Walls in Massive Hyper-Kähler Sigma Models
The general scalar potential of D-dimensional massive sigma-models with eight supersymmetries is found for D = 3, 4. These sigma models typically admit 1/2 supersymmetric domain wall solutions and we find, for a particular hyperKähler target, exact 1/4 supersymmetric static solutions representing a nontrivial intersection of two domain walls. We also show that the intersecting domain walls can ...
متن کاملVacua of Massive Hyper-Kähler Sigma Models of Non-Abelian Quotient
The Higgs branch of N = 2 supersymmetric gauge theories with nonAbelian gauge groups are described by hyper-Kähler (HK) nonlinear sigma models with potential terms. With the non-Abelian HK quotient by U(M) and SU(M) gauge groups, we give the massive HK sigma models that are not toric in the N = 1 superfield formalism and the harmonic superspace formalism. The U(M) quotient gives N !/[M !(N −M)!...

The Higgs branch of N = 2 supersymmetric gauge theories with non-Abelian gauge groups are described by hyper-Kähler (HK) nonlinear sigma models with potential terms. Using the non-Abelian HK quotient with respect to U(M) and SU(M) gauge groups, we derive the massive HK sigma models that are not toric in the N = 1 superfield formalism and the harmonic superspace formalism. The U(M) quotient give...
متن کاملMassive Nonlinear Sigma Models and BPS Domain Walls in Harmonic Superspace
Four-dimensional massive N = 2 nonlinear sigma models and BPS wall solutions are studied in the off-shell harmonic superspace approach in which N = 2 supersymmetry is manifest. The general nonlinear sigma model can be described by an analytic harmonic potential which is the hyper-Kähler analog of the Kähler potential in N = 1 theory. We examine the massive nonlinear sigma model with multi-cente...
متن کاملManifest Supersymmetry for BPS Walls in N = 2 Nonlinear Sigma Models
BPS equations and wall solutions are studied keeping (part of) supersymmetry (SUSY) manifest. Using N = 1 superfields, massive hyperKähler quotient is introduced to obtain massive N = 2 (8 SUSY) nonlinear sigma models in four dimensions with T CP n target manifold, which yield BPS wall solutions for the n = 1 case. We also describe massive hyper-Kähler quotient of T CP n by using the harmonic s...
