Celestial amplitudes in an ambidextrous basis
Abstract We start by constructing a conformally covariant improvement of the celestial light transform which keeps track of the mixing between incoming and outgoing states under finite Lorentz transformations in ℝ2,2. We then compute generic 2, 3 and 4-point celestial amplitudes for massless externa...
