Soft Photon, Gluon and Graviton Theorems in (A)dS from Conformal Invariance
Jiajie Mei, Yuyu Mo
We present new soft theorems for photon, gluon, and graviton correlators at tree level in (Anti)-de Sitter space. The results are derived by applying conformal Ward identities to c…

Regge factorization of tree-level QCD amplitudes using a minimal set of lightcone variables
Emmet P. Byrne, Vittorio Del Duca, Einan Gardi +2
We represent the multi-leg tree-level amplitudes of quarks and gluons using a minimal set of lightcone variables, which incorporate all on-shell and momentum conservation condition…

On-shell Bootstrap for n-gluons and gravitons scattering in (A)dS, Unitarity and Soft limit
Jiajie Mei, Yuyu Mo
We propose an algorithm to recursively bootstrap -point gluon and graviton Mellin-Momentum amplitudes in (A)dS spacetime using only three-point amplitude. We discover that gluon…
