摘要:
Bound states of BPS particles in five-dimensional N = 2 supergravity are counted by a topological index. We compute this bound state index exactly for two and three black holes as a function of the SU(2)(L) angular momentum. The required regulator for the infrared continuum of near-coincident black holes is chosen in accord with the enhanced superconformal symmetry.
