Moduli-Space Approximation for BPS Brane-Worlds
We develop the moduli-space approximation for the low energy regime of BPS-branes with a bulk scalar field to obtain an effective four-dimensional action describing the system. An arbitrary BPS potential is used and account is taken of the presence of matter in the branes and small supersymmetry breaking terms. The resulting effective theory is a bi-scalar tensor theory of gravity. In this theo...
متن کاملThe Moduli Space of BPS Domain Walls
N = 2 SQED with several flavors admits multiple, static BPS domain wall solutions. We determine the explicit two-kink metric and examine the dynamics of colliding domain walls. The multi-kink metric has a toric Kähler structure and we reduce the Kähler potential to quadrature. In the second part of this paper, we consider semi-local vortices on R×S1. We argue that, in the presence of a suitable...
متن کاملThe Moduli Space Metric for Well - separated BPS Monopoles
The Lagrangian for the motion of n well-separated BPS monopoles is calculated, by treating the monopoles as point particles with magnetic, electric and scalar charges. It can be reinterpreted as the Lagrangian for geodesic motion on the asymptotic region of the n-monopole moduli space, thereby determining the asymptotic metric on the moduli space. The metric is hyperkähler, and is an explicit e...
متن کاملModuli space of many BPS monopoles for arbitrary gauge groups.
We study the moduli space for an arbitrary number of BPS monopoles in a gauge theory with an arbitrary gauge group that is maximally broken to U(1). From the low energy dynamics of well-separated dyons we infer the asymptotic form of the metric for the moduli space. For a pair of distinct fundamental monopoles, the space thus obtained is R3 × (R1 ×M0)/Z where M0 is the Euclidean Taub-NUT manifo...
متن کاملGlobal Structure of Moduli Space for BPS Walls
We study the global structure of the moduli space of BPS walls in the Higgs branch of supersymmetric theories with eight supercharges. We examine the structure in the neighborhood of a special Lagrangian submanifold M , and find that the dimension of the moduli space can be larger than that naively suggested by the index theorem, contrary to previous examples of BPS solitons. We investigate BPS...
