Loop Amplitudes from Shadow Discontinuities: A Complete One-Loop Derivation in Celestial Holography
We establish that loop integrands in four-dimensional quantum gravity are encoded in the analytic structure of tree-level celestial CFT correlators via shadow discontinuities: residue extraction at th...
