Conformal structure of massless scalar amplitudes beyond tree level

Conformal structure of massless scalar amplitudes beyond tree level

Abstract We show that the one-loop on-shell four-point scattering amplitude of massless ϕ 4 scalar field theory in 4D Minkowski space time, when Mellin transformed to the Celestial sphere at infinity, transforms covariantly under the global conformal group (SL(2, ℂ)) on the sphere. The unitarity of...
