The four-dimensional (4D) Lorentz group SL (2, C) acts as the two-dimensional (2D) global conformal group on the celestial sphere at infinity where asymptotic 4D scattering states are …
We study solutions of the Klein-Gordon, Maxwell, and linearized Einstein equations in R 1, d+ 1 that transform as d-dimensional conformal primaries under the Lorentz group SO (1, d+ …

A bstract We develop the embedding formalism for conformal field theories, aimed at doing computations with symmetric traceless operators of arbitrary spin. We use an indexfree …

A bstract Carrollian conformal field theories (carrollian CFTs) are natural field theories on null infinity of an asymptotically flat spacetime or, more generally, geometries with conformal …

A bstract We reformulate the scattering amplitudes of 4D flat space gauge theory and gravity in the language of a 2D CFT on the celestial sphere. The resulting CFT structure exhibits an …
A bstract We derive a nonperturbative, convergent operator product expansion (OPE) for null- integrated operators on the same null plane in a CFT. The objects appearing in the …
A bstract We provide dramatic evidence that 'Mellin space'is the natural home for correlation functions in CFTs with weakly coupled bulk duals. In Mellin space, CFT correlators have …

A bstract For conformal field theories in arbitrary dimensions, we introduce a method to derive the conformal blocks corresponding to the exchange of a traceless symmetric tensor …
