IIB black hole horizons with fiveform flux and extended supersymmetry
Abstract
We classify under some assumptions the IIB black hole horizons with 5form flux preserving more than 2 supersymmetries. We find that the spatial horizon sections with nonvanishing flux preserving 4 supersymmetries are locally isometric either to S ^{1} × S ^{3} × T ^{4} or to S ^{1} × S ^{3} × K _{3} and the associated near horizon geometries are locally isometric to AdS _{3} × S ^{3} × T ^{4} and AdS _{3} × S ^{3} × K _{3}, respectively. The near horizon geometries preserving more than 4 supersymmetries are locally isometric to {{R}^{1,1}} × {T^8}.
