Missing Corner in the Sky: Massless Three-Point Celestial Amplitudes
Chi-Ming Chang, Wen-Jie Ma
We present the first computation of three-point celestial amplitudes in Minkowski space of massless scalars, photons, gluons, and gravitons. Such amplitudes were previously conside…
Shadow Celestial Amplitude
Chi-Ming Chang, Wei Cui, Wen-Jie Ma +2
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 o…
Scattering bound states in AdS
Wen-Jie Ma, Xinan Zhou
We initiate the study of bound state scattering in AdS space at the level of Witten diagrams. For concreteness, we focus on the case with only scalar fields and analyze several bas…
Feynman Rules for Scalar Conformal Blocks
Jean-François Fortin, Sarah Hoback, Wen-Jie Ma +2
We complete the proof of "Feynman rules" for constructing -point conformal blocks with external and internal scalars in any topology for arbitrary in any spacetime dimension…
