Amplitude Basis for Conformal Correlators
Hayden Lee, Xinkang Wang
We present a classification of conformally-invariant three-point tensor structures in dimensions that parallels the classification of three-particle scattering amplitudes in $d…

Momentum-space formulae for AdS correlators for diverse theories in diverse dimensions
Soner Albayrak, Savan Kharel, Xinkang Wang
In this paper, we explore correlators of a series of theories in anti-de Sitter space: we present comprehensive results for interactions involving scalars, gluons, and gravitons in…

Cosmological Double-Copy Relations
Hayden Lee, Xinkang Wang
We present differential double-copy relations between gluon and graviton three-point functions in (A)dS. We introduce a set of differential operators in (A)dS that naturall…
