Journal of High Energy Physics, 2023 We examine the BCFW recursion relations for celestial amplitudes and how they inform the celestial bootstrap program. We start by recasting the celestial incarnation of the BCFW shift as a generalization of the action of familiar asymptotic symmetries on

Journal of High Energy Physics, 2022 Celestial holography expresses S $$ \mathcal{S} $$ -matrix elements as correlators in a CFT living on the night sky. Poincaré invariance imposes additional selection rules on the allowed positions of operators.

Celestial diamonds: conformal multiplets in celestial CFT [PDF]
Journal of High Energy Physics, 2021 We examine the structure of global conformal multiplets in 2D celestial CFT. For a 4D bulk theory containing massless particles of spin s = 0 1 2 1 3 2 2 $$ \left\{0,\frac{1}{2},1,\frac{3}{2},2\right\} $$ we classify and construct all SL(2,ℂ) primary ...

Journal of High Energy Physics, 2023 We study scattering amplitudes in the shadow conformal primary basis, which satisfies the same defining properties as the original conformal primary basis and has many advantages over it. The shadow celestial amplitudes exhibit locality manifestly on the

The Grassmannian for celestial superamplitudes [PDF]
Journal of High Energy Physics, 2021 Recently, scattering amplitudes in four-dimensional Minkowski spacetime have been interpreted as conformal correlation functions on the two-dimensional celestial sphere, the so-called celestial amplitudes.

Celestial superamplitudes [PDF]
Physical Review D, 2021 We study celestial amplitudes in (super) Yang-Mills theory using a parametrization of the spinor helicity variables where their overall phase is not fixed by the little group action. In this approach the spin constraint h − ¯ h = J for celestial

Journal of High Energy PhysicsHolographic correlators on the celestial sphere of Minkowski space were recently defined in [1] as the extrapolation of bulk time-ordered correlation functions to the celestial sphere.

Celestial amplitude for 2d theory [PDF]
Journal of High Energy Physics, 2022 We explore celestial amplitude corresponding to 2d bulk S $$ \mathcal{S} $$ -matrix. We consider scalar particles with identical mass and show that the celestial amplitude becomes the fourier transform of the 2d S $$ \mathcal{S} $$ -matrix written in the
