چکیده

Domain walls play a central role in a subject of recent interest, the braneworld scenario. In particular, BPS domain walls are investigated in detail in D = 4, N = 1 SUSY theories. We should consider hypermultiplets to realize D = 4, N = 1 SUSY theory on the world-volume. In order to have a potential with discrete degenerate vacua, they must have gauge interaction, or nonlinearity of kinetic term, namely nonlinear sigma models (NLSM). The latter case can be obtained from the former case in the strong gauge coupling limit. A lot of interesting solitons have been discussed in hypermultiplets with or without taking this limit. In this talk, the hyper-Kähler (HK) quotient method is generalized to the massive models and the BPS domain wall in the simplest case is given. Keeping essential properties of eight supercharges, we discuss a simpler and

D-brane Configurations for Domain Walls and Their Webs

Supersymmetric U(NC) gauge theory with NF massive hypermultiplets in the fundamental representation admits various BPS solitons like domain walls and their webs. In the first part we show as a review of the previous paper [1] that domain walls are realized as kinky fractional D3-branes interpolating between separated D7-branes. In the second part we discuss brane configurations for domain wall ...

Bent BPS domain walls of D = 5 N = 2 gauged supergravity coupled to hypermultiplets

Within D=5 N=2 gauged supergravity coupled to hypermultiplets we derive consistency conditions for BPS domain walls with constant negative curvature on the wall. For such wall solutions to exist, the covariant derivative of the projector, governing the constraint on the Killing spinor, has to be non-zero and proportional to the cosmological constant on the domain walls. We also prove that in th...

Bulk–Brane Duality in Field Theory

We consider (3+1)-dimensional N = 2 supersymmetric QED with two flavors of fundamental hypermultiplets. This theory supports 1/2-BPS domain walls and flux tubes (strings), as well as their 1/4-BPS junctions. The effective (2+1)-dimensional theory on the domain wall is known to be a U(1) gauge theory. Previously, the wall–string junctions were shown to play the role of massive charges in this th...

Domain walls in five dimensional supergravity with non-trivial hypermultiplets

We study BPS domain wall solutions of 5-dimensional N = 2 supergravity where isometries of the hypermultiplet geometry have been gauged. We derive the corresponding supersymmetric flow equations and define an appropriate c-function. As an example we discuss a domain wall solution of Freedman, Gubser, Pilch and Warner which is related to a RG-flow in a dual superconformal field theory.
