# Celestial correlators ## General procedures - [[2019#Law, Zlotnikov]]: performs Mellin transformation and shows that low-point correlators are distributional - [[2023#Sleight, Taronna]] and [[2024#Iacobacci, Sleight, Taronna]]: proposes to use time-ordered correlators as a starting point in [[0010 Celestial holography|celestial CFT]] rather than scattering amplitudes, given the latter suffers from a divergence in the integration step - [[2023#Mason, Ruzziconi, Srikant]]: Carollian - [[2024#Adamo, Bu, Tourkine, Zhu]]: eikonal - [[2024#Jorstad, Pasterski]]: a soft contribution that is usually dropped ## Dealing with distributional amplitudes - [[2023#Ball, De, Srikant, Volovich]]: using scalar field to remove the distributional singularity - [[2023#Melton, Sharma, Strominger (Dec)]]: decomposition of celestial amplitudes in terms of leaf amplitudes on AdS$_3$ slices - [[2024#Pano, Borji]]: rigorously define the [[0079 Mellin transform|Mellin transform]] of tempered distributions
