Description

Celestial holography conjectures a duality between a theory of quantum gravity living in the bulk of an asymptotically flat spacetime and a codimension 2 conformal field theory living on its boundary. I will present some motivation to this correspondence, namely by looking at the soft sector of scattering amplitudes and their relation to asymptotic symmetries. These can be seen as generated by 2D boundary operators which I will show how to construct explicitly from 4D bulk operators, in the context of fermionic symmetries. Finally I will discuss the global conformal multiplet structure of the boundary CFT which is more commonly referred to as celestial CFT.
