In this paper we construct the five-parameter generating solution of N = 8 BPS regular supergravity black holes as a five-parameter solution of the N = 2 STU model. Our solution has a simpler form with respect to previous constructions which have already appeared in the literature and moreover, through the embedding [SL(2)](3) subset of SV(3, 3) subset of E-7(7) discussed in previous papers, the action of the U-duality group is well defined. This allows us to reproduce via U-duality rotations any other solution, such as those corresponding to R-R black holes whose microscopic description is given by intersecting D-branes.

Abstract
In this paper we construct the five-parameter generating solution of N = 8 BPS regular supergravity black holes as a five-parameter solution of the N = 2 STU model. Our solution has a simpler form with respect to previous constructions which have already appeared in the literature and moreover, through the embedding [SL(2)](3) subset of SV(3, 3) subset of E-7(7) discussed in previous papers, the action of the U-duality group is well defined. This allows us to reproduce via U-duality rotations any other solution, such as those corresponding to R-R black holes whose microscopic description is given by intersecting D-branes.| File | Dimensione | Formato | |
