Overlapping Branes in M -Theory
We construct new supersymmetric solutions of D=11 supergravity describing n orthogonally “overlapping” membranes and fivebranes for n=2,. . . ,8. Overlapping branes arise after separating intersecting branes in a direction transverse to all of the branes. The solutions, which generalize known intersecting brane solutions, preserve at least 2−n of the supersymmetry. Each pairwise overlap involve...
متن کاملCoupling of M–branes in M–theory
Coupling of a membrane and a five-brane to the bosonic sector of D = 11 supergravity is considered. The five–brane is a dyonic object which carries both an electric and a magnetic charge of the D = 11 three-form gauge field A, and it couples not only to A but also minimally couples to a six-form field A dual to A. This implies that the 5-brane should more naturally couple to a version of D = 11...
متن کاملColliding Branes in Heterotic M-Theory
We study the collision of two flat, parallel end-of-the-world branes in heterotic M-theory. By insisting that there is no divergence in the Riemann curvature as the collision approaches, we are able to single out a unique solution possessing the local geometry of (2d compactified Milne)/Z2 × R3, times a finite-volume CalabiYau manifold in the vicinity of the collision. At a finite time before a...
متن کاملMassless 3 - branes in M - theory
We construct M3-brane solutions in D = 11 supergravity. They can be viewed as deformations of backgrounds taking the form of a direct product of four-dimensional Minkowski spacetime and a non-compact Ricci-flat manifold of G 2 holonomy. Although the 4-form field strength is turned on it carries no charge, and the 3-branes are correspondingly massless. We also obtain 3-branes of a different type...
متن کاملFive-branes in M(atrix) Theory
We propose a construction of five-branes which fill both light-cone dimensions in Banks, Fischler, Shenker and Susskind’s matrix model of M theory. We argue that they have the correct long-range fields and spectrum of excitations. We prove Dirac charge quantization with the membrane by showing that the five-brane induces a Berry phase in the membrane world-volume theory, with a familiar magneti...
