Abstract
Abstract: This paper presents a worldsheet theory describing holomorphic maps to twistor space with N fermionic directions. The theory is anomaly free when N = 8. Via the Penrose transform, the vertex operators correspond to an N = 8 Einstein supergravity multiplet. In the first instance, the theory describes gauged supergravity in AdS4. Upon taking the flat space, ungauged limit, the complete classical S-matrix is recovered from worldsheet correlation functions.
