An AdS3 Dual for Supersymmetric MHV Celestial Amplitudes
Abstract
We propose a generalisation of the Wess-Zumino-Novikov-Witten (WZNW) model, formulated on a holomorphic extension of supersymmetric three-dimensional Anti-de Sitter (AdS3) space, which holographically reproduces the tree-level maximally-helicity-violating (MHV) celestial amplitudes for gravitons in N=8 supergravity and gluons in four-dimensional N=4 supersymmetric Yang-Mills (SYM) theory.
