Black Brane World from Gravitating Half  -lump

Abstract: We study O(N + 1) nonlinear σ-model in (p + 1 + N )-dimensional curved spacetime with a negative cosmological constant, and find a new σ-lump solution with half-integer winding and divergent energy. When the spatial structure of N extra-dimensions is determined by this global defect, a black σp-brane surrounded by the degenerated horizon is formed and its near-horizon geometry is identified as a warp geometry of a cigar type.

“…(3.7) exists even in higher extra-dimensions with unit topological charge (n = 1). The previous analysis of the black brane world based on half σ-lumps in O(N + 1) nonlinear σ-model [23,19] provides a positive hint on a short scalar hair, of which results were independent of the extra-dimensions N .…”
