Self-Dual N=8 Supergravity as Closed N=2(4) Strings | | W. Siegel
; | | Date: |
13 Jul 1992 | | Journal: | Phys.Rev. D47 (1993) 2504-2511 | | Subject: | hep-th | | Abstract: | As open N=2 or 4 strings describe self-dual N=4 super Yang-Mills in 2+2 dimensions, the corresponding closed (heterotic) strings describe self-dual ungauged (gauged) N=8 supergravity. These theories are conveniently formulated in a chiral superspace with general supercoordinate and local OSp(8|2) gauge invariances. The super-light-cone and covariant-component actions are analyzed. Because only half the Lorentz group is gauged, the gravity field equation is just the vanishing of the torsion. | | Source: | arXiv, hep-th/9207043 | | Other source: | [GID 434568] pmid10015844 | | Services: | Forum | Review | PDF | Favorites | |
