IIB black hole horizons with five-form flux and extended supersymmetry

Journal article, 2011

We classify under some assumptions the IIB black hole horizons with 5-form flux preserving more than 2 supersymmetries. We find that the spatial horizon sections with non-vanishing flux preserving 4 supersymmetries are locally isometric either to S(1) x S(3) x T(4) or to S(1) x S(3) x K(3) and the associated near horizon geometries are locally isometric to AdS(3) x S(3) x T(4) and AdS(3) x S(3) x K(3), respectively. The near horizon geometries preserving more than 4 supersymmetries are locally isometric to R(1,1) x T(8).
