Maths HEP Lunchtime Seminars: Do Supersymmetric Anti de Sitter Black Rings Exist?
2 February 2007 13:00 in CM221
According to the AdS/CFT correspondence, supersymmetric AdS5 black holes should correspond to 1/16 BPS states in large N Super Yang-Mills theory. Such states are labelled by five independent charges, but the most general known black hole solution is described by only four. It is therefore important to investigate whether other black hole solutions, such as black rings, could exist. In this talk I will describe work done with James Lucietti and Harvey Reall in which we determined the most general near horizon geometry of a supersymmetric AdS5 black hole, assuming only the existence of two rotational symmetries. The near horizon is topologically spherical. Although we found a near horizon corresponding to that of a black ring, it suffers from a conical singularity.
