On the simplicity of de Sitter correlators
Chandramouli Chowdhury, Song He, Yong-Xiang Su +1
Motivated by recent evidence that equal-time correlators can be simpler than the corresponding wavefunction coefficients, we study de Sitter correlators in conformally coupled $Ï^…

Hidden simplicity in AdS spinning Mellin amplitudes via scaffolding
Song He, Xiang Li, Yuyu Mo +1
We uncover surprising hidden simplicity in Mellin amplitudes for tree-level AdS holographic correlators for spinning operators, such as AdS "gluons" and "gravitons" (spin 1 and 2).…

On differential operators for scalar-scaffolded gluons
Jin Dong, Yong-Xiang Su, Dongyu Yang
Recently, based on the curve-integral formulation for stringy Tr amplitudes, a combinatorial formulation for Yang-Mills amplitudes has been proposed which describes gluons us…
