Celestial amplitude for 2d theory
Abstract We explore celestial amplitude corresponding to 2d bulk S $$ \mathcal{S} $$ -matrix. We consider scalar particles with identical mass and show that the celestial amplitude becomes the fourier transform of the 2d S $$ \mathcal{S} $$ -matrix written in the rapidity variable. We translate the...
