Abstract We demonstrate that in addition to the usual fourth-rank superfield ( W abcd ) which describes the on-shell 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 off-shell formulation. Our result indicates that eleven-dimensional supergravity… Expand
