Intersecting black attractors in 8D N=1 supergravity

Abstract

We study intersecting extremal black attractors in non chiral 8D N = 1 supergravity with moduli space SO(2,N ) SO(2)×SO(N ) × SO (1, 1) and work out explicitly the attractor mechanism for various black p-brane configurations with the typical near horizon geometries AdS p+2 × S m × T 6−p−m . We also give the classification of the solutions of the attractor equations in terms of the SO (N − k) subgroups of SO (2) × SO (N ) symmetry of the moduli space as well as their interpretations in terms of both heterotic string on 2-torus and its type IIA dual. Other features such as non trivial SO(1, 7) central charges Z µ 1 ...µ p in 8D N = 1 supergravity and their connections to p-form gauge fields are also given.
