A New Angle on Intersecting Branes in Infinite Extra Dimensions
نویسنده
چکیده
I construct solutions to Einstein’s equations in 6 dimensions with bulk cosmological constant and intersecting 4-branes. Solutions exist for a continuous range of 4-brane tension, with long distance gravity localized to a 3+1 dimensional Minkowski intersection, provided that the additional tension of the intersection satisfies one condition. ∗[email protected]

Intersecting M-branes as Four-Dimensional Black Holes
We present two 1/8 supersymmetric intersecting p-brane solutions of 11-dimensional supergravity which upon compactification to four dimensions reduce to extremal dyonic black holes with finite area of horizon. The first solution is a configuration of three intersecting 5-branes with an extra momentum flow along the common string. The second describes a system of two 2-branes and two 5-branes. R...
متن کاملTASI Lectures on Extra Dimensions and Branes∗
This is a pedagogical introduction into theories with branes and extra dimensions. We first discuss the construction of such models from an effective field theory point of view, and then discuss large extra dimensions and some of their phenomenological consequences. Various possible phenomena (split fermions, mediation of supersymmetry breaking and orbifold breaking of symmetries) are discussed...
متن کاملBrane Networks in AdS Space
We present static solutions to Einstein’s equations corresponding to the most general network of N orthogonal families of (2 + N)-branes in (4 +N)dimensional AdS spacetimes. The bulk cosmological constant can take a different value in each cell enclosed by intersecting branes and the extra dimensions can be compact or noncompact. In each family of branes the interbrane spacing is arbitrary. The...
متن کاملInflating Intersecting Branes and Remarks on the Hierarchy Problem
We generalize solutions of Einstein’s equations for intersecting branes in higher dimensional spacetimes to the nonstatic case, modeling an expanding universe. The relation between the Hubble rate, the brane tensions, and the bulk cosmological constant is similar to the case of a single 3-brane in a 5-dimensional spacetime. We discuss how cosmological expansion can be reconciled with the Randal...
متن کاملSidestepping the Cosmological Constant with Football-Shaped Extra Dimensions
We present an exact solution for a factorizable brane-world spacetime with two extra dimensions and explicit brane sources. The compactification manifold has the topology of a two-sphere, and is stabilized by a bulk cosmological constant and magnetic flux. The geometry of the sphere is locally round except for conical singularities at the locations of two antipodal branes, deforming the sphere ...
