Worldline Formalism, Eikonal Expansion and the Classical Limit of Scattering Amplitudes
Siddarth Ajith, Yuchen Du, Ravisankar Rajagopal +1
We revisit the fundamentals of two different methods for calculating classical observables: the eikonal method, which is a scattering amplitude-based method, and the worldline quan…

Worldline Proof of Eikonal Exponentiation
Yuchen Du, Siddarth Ajith, Ravisankar Rajagopal +1
In this paper, working in the eikonal approximation, we present a proof for the exponentiation of the 2-body eikonal phase to {\it all orders in the eikonal expansion}, for scalar…
