Contribution

It provides explicit analysis of the attractor mechanism for various black p-branes in 8D supergravity with detailed near horizon geometries and M-theory interpretations.

Findings

Explicit attractor solutions for p=0,1,2,3,4 branes.

Connections between supergravity solutions and wrapped M-branes.

Enhanced understanding of extremal black brane configurations in 8D.

Abstract

Motivated by the new higher D-supergravity solutions on intersecting attractors obtained by Ferrara et al. in [Phys.Rev.D79:065031-2009], we focus in this paper on 8D maximal supergravity with moduli space [SL(3,R)/SO(3)]x[SL(2,R)/SO(2)] and study explicitly the attractor mechanism for various configurations of extremal black p- branes (anti-branes) with the typical near horizon geometries AdS_{p+2}xS^{m}xT^{6-p-m} and p=0,1,2,3,4; 2<=m<=6. Interpretations in terms of wrapped M2 and M5 branes of the 11D M-theory on 3-torus are also given. Keywords: 8D supergravity, black p-branes, attractor mechanism, M-theory.
