Abstract We demonstrate the equivalence between observables in the KMOC and worldline formalisms for classical general relativity, highlighting the relation between the initial conditions in the two frameworks and how the Keldysh-Schwinger in-in form

On an exponential representation of the gravitational S-matrix

Autor: Poul H. Damgaard, Ludovic Planté, Pierre Vanhove

Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 11, Pp 1-25 (2021)

Abstract An exponential representation of the S-matrix provides a natural framework for understanding the semi-classical limit of scattering amplitudes. While sharing some similarities with the eikonal formalism it differs from it in details. Computa

The interactions of gravitons with spin-1 matter are calculated in parallel with the well known photon case. It is shown that graviton scattering amplitudes can be factorized into a product of familiar electromagnetic forms, and cross sections for va
