A Microscopical Description of Giant Gravitons | | Bert Janssen

22 Jul 2002 | | Journal: | Nucl.Phys. B658 (2003) 281-299 DOI: 10.1016/S0550-3213(03)00185-8 | | Subject: | hep-th | | Abstract: | We construct a non-Abelian world volume effective action for a system of multiple M-theory gravitons. This action contains multipole moment couplings to the eleven-dimensional background potentials. We use these couplings to study, from the microscopical point of view, giant graviton configurations where the gravitons expand into an M2-brane, with the topology of a fuzzy 2-sphere, that lives in the spherical part of the AdS_7 x S^4 background or in the AdS part of AdS_4 x S^7. When the number of gravitons is large we find perfect agreement with the Abelian, macroscopical description of giant gravitons given in the literature. | | Source: | arXiv, hep-th/0207199 | | Services: | Forum | Review | PDF | Favorites | |
