Distributional celestial amplitudes
Abstract Scattering amplitudes are tempered distributions, which are defined through their action on functions in the Schwartz space S ℝ $$ \mathcal{S}\left(\mathbb{R}\right) $$ by duality. For massless particles, their conformal properties become manifest when considering their Mellin transform. Th...
