Singularity structure of the four point celestial leaf amplitudes

Singularity structure of the four point celestial leaf amplitudes

Abstract In this paper, we study the four-point celestial leaf amplitudes of massless scalar and MHV gluon scattering. These leaf amplitudes are non-distributional decompositions of the celestial amplitudes associated with a hyperbolic foliation of the Klein spacetime. Bulk scale invariance imposes...
