Celestial Mellin Amplitudes II: Spin-1 and Spin-2 Exchange, and Beyond
Sébastien Malherbe, Paolo Pergola, Charlotte Sleight +1
We further develop celestial Mellin amplitudes arXiv:2412.11992 to capture the exchange of particles with spin. For massless external scalar fields, we derive closed-form celestial…
(Non-)Conserved Currents and Cosmological Correlators
Charlotte Sleight, Massimo Taronna
We study the fate of global symmetries at the late-time boundary of de Sitter space. In anti-de Sitter space, bulk gauge symmetries generally correspond to conserved global current…
Cosmological Correlators in Gauge Theory and Gravity from EAdS
Md. Abhishek, Charlotte Sleight, Massimo Taronna
In this work we examine in more detail the map between late-time correlators in de Sitter space and boundary correlators in Euclidean anti-de Sitter space, elaborating on the gener…
Conformal Partial Wave Expansion of Celestial Correlators
Francesca Pacifico, Charlotte Sleight, Massimo Taronna
A novel definition of holographic correlation functions on the celestial sphere of Minkowski space was recently introduced in arXiv:2301.01810 as the extrapolation of bulk time-ord…
