Abstract:

A universal relationship between asymptotic symmetries, QFT soft theorems, and low energy observables has reinvigorated attempts at flat space holography.  In this talk we introduce a map from 4d S-matrix elements to 2d correlators in the putative dual Celestial CFT.  In particular, we will focus on recent progress towards understanding elements of the IR triangle from the perspective of our Celestial CFT.

 

Note the unusual start time!
