The Cosmological -shift
Carolina Figueiredo, Jiajie Mei, Yuyu Mo +1
We consider the extension of the -shift connecting Tr and pion amplitudes to observables in cosmology. We start in flat-space and explain how one can extract the pion wav…
All-Plus QED Wavefunctions in de Sitter Space
Song He, Jiajie Mei, Yuyu Mo
We present a compact all-multiplicity formula for tree-level late-time wavefunction coefficients of scalar QED in four-dimensional de Sitter space, with a conformally coupled charg…
From Cosmological Cuts to Yang--Mills Wavefunctions in de Sitter Space
Song He, Jiajie Mei, Yuyu Mo
We study tree-level Yang--Mills wavefunctions in four-dimensional de Sitter space using their discontinuities. Cosmological cuts factorize gluon discontinuities into lower-point wa…
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).…
