An integer basis for celestial amplitudes
Jordan Cotler, Noah Miller, Andrew Strominger
Abstract
A bstract We present a discrete basis of solutions of the massless Klein-Gordon equation in 3 + 1 Minkowski space which transform as π°π©(2, β) Lorentz/conformal primaries and descendants, and whose elements all have integer conformal dimension. We show that the basis is complete in the sense that the Wightman function can be expressed as a quadratic sum over the basis elements.
