Moduli spaces for four- and five-dimensional black holes - art. no. 064023

We propose a universal expression for the moduli metric of a class of four- and five-dimensional black holes which preserve at least four supersymmetr ies. These include the black holes that are associated with various interse cting branes in ten and eleven dimensions, the electrically charged black h oles of N = 2, D = 5 and N = 2, D = 4 supergravities with any number of vec tor multiplets, and dyonic black holes of N = 2, D = 4 supergravity. The mo duli metric of electrically charged N = 2, D = 4 black holes coupled to any number of vector multiplets is explicitly computed. We also investigate th e superconformal symmetries of the black hole moduli spaces for small black hole separations.
