Towards a manifestly supersymmetric action for 11-dimensional supergravity

Artikel i vetenskaplig tidskrift, 2009

We investigate the possibility of writing a manifestly supersymmetric action for 11-dimensional supergravity. The construction involves an explicit relation between the fields in the super-vielbein and the super-3-form, and uses non-minimal pure spinors. A simple cubic interaction term for a single scalar superfield is found.
