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…
Words to describe a black hole
Chi-Ming Chang, Ying-Hsuan Lin
We revamp the constructive enumeration of 1/16-BPS states in the maximally supersymmetric Yang-Mills in four dimensions, and search for ones that are not of multi-graviton form. A…
Topological Defect Lines in Two Dimensional Fermionic CFTs
Chi-Ming Chang, Jin Chen, Fengjun Xu
We consider topological defect lines (TDLs) in two-dimensional fermionic conformal field theories (CFTs). Besides inheriting all the properties of TDLs in bosonic CFTs, TDLs in fer…
