Toward an offshell 11D supergravity limit of Mtheory
Abstract
We demonstrate that in addition to the usual fourthrank superfield ( W_{abcd}) which describes the onshell theory, a spinor superfield ( J_{α}) can be introduced into the 11D geometrical tensors with engineering dimensions less or equal to one in such a way to satisfy the Bianchi identities in superspace. The components arising from J_{α} are identified as some of the auxiliary fields required for a full offshell formulation. Our result indicates that elevendimensional supergravity does not have to be completely onshell. The κsymmetry of the supermembrane action in the presence of our partial offshell supergravity background is also confirmed. Our modifications to elevendimensional supergravity theory are thus likely relevant for Mtheory. We suggest our proposal as a significant systematic offshell generalization of elevendimensional supergrravity theory.
