An 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...
متن کاملAn exact BPS wall solution in Five Dimensional Supergravity
In five-dimensional supergravity, an exact solution of BPS wall is found for a gravitational deformation of the massive Eguchi-Hanson nonlinear sigma model. The warp factor decreases for both infinities of the extra dimension. Thin wall limit gives the Randall-Sundrum model without fine-tuning of input parameters. We also obtain wall solutions with warp factors which are flat or increasing in o...
متن کاملAn Exact Solution of BPS Junctions and Its Properties
We have obtained an exact solution for the BPS domain wall junction for a N = 1 supersymmetric theory in four dimensions and studied its properties. The model is a simplified version of the N = 2 SU(2) gauge theory with Nf = 1 broken to N = 1 by the mass of the adjoint chiral superfield. We define mode equations and demonstrate explicitly that fermion and boson with the same mass have to come i...
متن کاملExact BPS monopole solution in a self - dual background
An exact one monopole solution in a uniform self-dual background field is obtained in the BPS limit of the SU(2) Yang-Mills-Higgs theory by using the inverse scattering method.
متن کاملDomain 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...
