Celestial amplitudes from UV to IR
A bstract Celestial amplitudes represent 4D scattering of particles in boost, rather than the
usual energy-momentum, eigenstates and hence are sensitive to both UV and IR physics …

Celestial holography
Celestial holography proposes a duality between the gravitational $\mathcal {S} $-matrix
and correlators in a conformal field theory living on the celestial sphere. In this white paper …

4D scattering amplitudes and asymptotic symmetries from 2D CFT
C Cheung, A de la Fuente, R Sundrum - Journal of High Energy Physics, 2017 - Springer
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 …
