Group Meeting Talk: BMS Symmetry and OPE of Celestial CFTs

Title : BMS Symmetry and OPE of Celestial CFTs

Speaker: Sudip Ghosh

Abstract: The holographic dual of quantum gravitational theories in asymptotically flat spacetimes has recently been conjectured to be the so called celestial conformal field theories whose correlation functions are Mellin transforms of bulk scattering amplitudes. In this talk I will discuss aspects of a derivation of the OPE in these CFTs from the collinear singularities of graviton scattering amplitudes and the constraints of BMS symmetries on the OPE coefficients.
