A Solitonic 3 - Brane in 6 D Bulk

چکیده
We construct a solitonic 3-brane solution in the 6-dimensional EinsteinHilbert-Gauss-Bonnet theory with a (negative) cosmological term. This solitonic brane world is δ-function-like. Near the brane the metric is that for a product of the 4-dimensional flat Minkowski space with a 2-dimensional “wedge” with a deficit angle (which depends on the solitonic brane tension). Far from the brane the metric approaches that for a product of the 5dimensional AdS space and a circle. This solitonic solution exists for a special value of the Gauss-Bonnet coupling (for which we also have a δ-function-like codimension-1 solitonic solution), and the solitonic brane tension can take values in a continuous range. We discuss various properties of this solitonic brane world, including coupling between gravity and matter localized on the brane.

Time-like Extra Dimensions without Tachyons or Ghosts
Some time ago Dvali, Gabadadze and Senjanović [1] discussed brane world scenarios with time-like extra dimensions. In this paper we construct a solitonic 3-brane solution in the 5-dimensional Einstein-Hilbert-Gauss-Bonnet theory with the space-time signature (−,+,+,+,−). The direction transverse to the brane is the second time-like direction. The solitonic brane is δ-function like, and has the ...
متن کاملSolitonic brane inflation
We present a new type of brane inflation motivated by multikink solitonic solutions of a scalar field in five dimensions. In the thin brane limit, we analyze a nonstatic configuration in which the distance between two parallel domain walls decreases. We show that the ensuing spacetime is inflationary, both on the branes, and, for certain potentials, in the bulk. We argue that this inflationary ...
متن کاملSolitonic Brane World with Completely Localized (Super)Gravity
We construct a solitonic 3-brane solution in the 5-dimensional EinsteinHilbert-Gauss-Bonnet theory. This solitonic brane is δ-function like, and has the property that gravity is completely localized on the brane. That is, there are no propagating degrees of freedom in the bulk, while on the brane we have purely 4-dimensional Einstein gravity. Thus, albeit the classical background is 5-dimension...
متن کاملMass hierarchy from recoiling D-branes
Using conformal field theory methods we construct a metric that describes the distortion of space-time surrounding a D~irichlet!-brane ~solitonic! defect after being struck by another D-brane. By viewing our four-dimensional universe as such a struck brane, embedded in a five-dimensional space-time, we argue on the appearance of a band of massive Kaluza-Klein excitations for the bulk graviton w...
متن کاملD-branes and Closed String Field Theory
D-branes have been studied for many years and used to reveal nonperturbative aspects of string theory. As A. Sen argued, D-branes can be realized as soliton solutions in open string field theory. Now some of his conjectures1 have been proved analytically2 in Witten’s open string field theory.3 What we would like to discuss here is how D-branes can be realized in closed string field theory.
