Query: Black Brane World from Gravitating Half $\sigma$-lump   We study O($N+1$) nonlinear $\sigma$-model in $(p+1+N)$-dimensional curved
spacetime with negative cosmological constant, and find a new $\sigma$-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
$\sigma p$-brane surrounded by the degenerated horizon is formed and its
near-horizon geometry is identified as a warp geometry of cigar type.
