Composite M-branes Original Research Article

We present new supersymmetric solutions of D = 11 supergravity obtained by intersecting the brane configuration interpreted as a 2-brane lying within a 5-brane. Some of these solutions can be boosted along a common string and/or superposed with a Kałuza-Klein monopole. We also present a new embedding of the extreme four-dimensional dyonic black hole with finite horizon area. These solutions are a consequence of a rather simple set of rules that allow us to construct the composite M-branes.
