Domain Wall Junctions are 1/4-BPS States
We study N = 1 SUSY theories in four dimensions with multiple discrete vacua, which admit solitonic solutions describing segments of domain walls meeting at one-dimensional junctions. We show that there exist solutions preserving one quarter of the underlying supersymmetry – a single Hermitian supercharge. We derive a BPS bound for the masses of these solutions and construct a solution explicit...
متن کاملBPS Domain Wall Junctions in Infinitely Large Extra Dimensions
We consider models of scalar fields coupled to gravity which are higher-dimensional generalizations of four dimensional supergravity. We use these models to describe domain wall junctions in an antide Sitter background. We derive Bogomolnyi equations for the scalar fields from which the walls are constructed and for the metric. From these equations a BPS-like formula for the junction energy can...

متن کاملOn Superpotential and BPS domain wall in SQCD and MQCD
We examine the decoupling properties of the N=2 SQCD vacua when the adjoint mass term is turned on and then the N=1 limit is taken. The BPS domain wall tension in N=1 MQCD and SQCD is also examined. The correspondence of the MQCD integrals with the superpotential and the gaugino condensate is shown. [email protected]
متن کاملAn Exact Solution of BPS Domain Wall Junction
An exact solution of domain wall junction is obtained in a fourdimensional N = 1 supersymmetric U(1) × U(1)′ gauge theory with three pairs of chiral superfields which is motivated by the N = 2 SU(2) gauge theory with one flavor perturbed by an adjoint scalar mass. The solution allows us to evaluate various quantities including a new central charge Yk associated with the junction besides Zk whic...
