Abstract:  In this paper, we firstly review the celestial holographic. Then we apply celestial holography to the 2d Bullough-Dodd model. We compute the conformal correlator dual to the 2d scattering amplitude of the Bullough-Dodd model at the leading order, and verify its unitarity.


Key words: celestial holography, Bullogh-Dodd model, scatter amplitude
