WebAug 22, 2024 · We consider 2-2 scattering in four spacetime dimensions in Celestial variables. Using the crossing symmetric dispersion relation (CSDR), we recast the Celestial amplitudes in terms of crossing symmetric partial waves. These partial waves have spurious singularities in the complex Celestial variable, which need to be removed … WebSep 28, 2024 · This work considers manifestly crossing symmetric dispersion relations for Mellin amplitudes of scalar four point correlators in conformal field theories and employs certain "locality" constraints replacing the requirement of crossing symmetry in the usual fixed-t dispersion relation. Webcrossing symmetric formula is often a better representation than the conventional dispersion relation. For the situation … federal tss shotshells for sale
