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