Harmonic superpositions of Mbranes
Abstract
We present solutions describing supersymmetric configurations of 2 or 3 orthogonally intersecting 2branes and 5branes of D = 11 supergravity. The configurations which preserve {1}/{4} or {1}/{8} of maximal supersymmetry are 2⊥2, 5⊥5, 2⊥5, 2⊥2⊥2, 5⊥5⊥5, 2⊥2⊥5 and 2⊥5⊥5 (2⊥2 stands for orthogonal intersection of two 2branes over a point, etc.; pbranes of the same type intersect over (p2)branes). There exists a simple rule which governs the construction of composite supersymmetric pbrane solutions in D = 10 and 11 with a separate harmonic function assigned to each constituent {1}/{2} supersymmetric pbrane. The resulting picture of intersecting pbrane solutions complements their Dbrane interpretation in D = 10 and seems to support possible existence of a D = 11 analogue of Dbrane description. The D = 11 solution describing intersecting 2brane and 5brane reduces in D = 10 to a type 11 string solution corresponding to a fundamental string lying within a solitonic 5brane (which further reduces to an extremal D = 5 black hole). We also discuss a particular D = 11 embedding of the extremal D = 4 dyonic black hole solution with finite area of horizon.
