Non - BPS Walls and Their Stability in 5 D Supersymmetric Theory

چکیده
An exact solution of non-BPS multi-walls is found in supersymmetric massive T ⋆(CP) model in five dimensions. The non-BPS multi-wall solution is found to have no tachyon. Although it is only metastable under large fluctuations, we can give topological stability by considering a model with a double covering of the T ⋆(CP) target manifold. TheN = 1 supersymmetry preserved on the four-dimensional world volume of one wall is broken by the coexistence of the other wall. The supersymmetry breaking is exponentially suppressed as the distance between the walls increases. e-mail address: [email protected] e-mail address: [email protected], Special Postdoctoral Researcher e-mail address: [email protected]

Wall-crossing made smooth
In D = 4,N = 2 theories on R, the index receives contributions not only from single-particle BPS states, counted by the BPS indices, but also from multi-particle states made of BPS constituents. In a recent work [1], a general formula expressing the index in terms of the BPS indices was proposed, which is smooth across walls of marginal stability and reproduces the expected single-particle cont...
متن کاملBPS D-branes on Non-supersymmetric Cycles
In certain regions of the moduli space of K3 and Calabi-Yau manifolds, D-branes wrapped on non-supersymmetric cycles may give rise to stable configurations. We show that in the orbifold limit, some of these stable configurations can be described by solvable boundary conformal field theories. The world-volume theory of N coincident branes of this type is described by a non-supersymmetric U(N) ga...
متن کاملWebs of Walls
Webs of domain walls are constructed as 1/4 BPS states in d = 4, N = 2 supersymmetric U(NC) gauge theories with NF hypermultiplets in the fundamental representation. Web of walls can contain any numbers of external legs and loops like (p, q) string/5-brane webs. We find the moduli space M of a 1/4 BPS equation for wall webs to be the complex Grassmann manifold. When moduli spaces of 1/2 BPS sta...
متن کاملWalls of Marginal Stability and Dyon Spectrum in N = 4 Supersymmetric String
The spectrum of quarter BPS dyons in N = 4 supersymmetric string theories can change as the asymptotic moduli cross walls of marginal stability on which the dyon can break apart into a pair of half BPS states. In this paper we classify these marginal stability walls and examine this phenomenon in the context of exact dyon spectrum found in a class of N = 4 supersymmetric string theories. We arg...
