Bethe-Salpeter equation for classical gravitational bound states
Tim Adamo, Riccardo Gonzo
The Bethe-Salpeter equation is a non-perturbative, relativistic and covariant description of two-body bound states. We derive the classical Bethe-Salpeter equation for two massive…
All-order celestial OPE in the MHV sector
Tim Adamo, Wei Bu, Eduardo Casali +1
On-shell kinematics for gluon scattering can be parametrized with points on the celestial sphere; in the limit where these points collide, it is known that tree-level gluon scatter…
Higher-spin Yang-Mills, amplitudes and self-duality
Tim Adamo, Tung Tran
The existence of interacting higher-spin theories is tightly constrained by many no-go theorems. In this paper, we construct a chiral, higher-spin generalization of Yang-Mills theo…
All order gravitational waveforms from scattering amplitudes
Tim Adamo, Andrea Cristofoli, Anton Ilderton +1
Waveforms are classical observables associated with any radiative physical process. Using scattering amplitudes, these are usually computed in a weak-field regime to some finite or…
The ultrarelativistic limit of Kerr
Tim Adamo, Andrea Cristofoli, Piotr Tourkine
The massless (or ultrarelativistic) limit of a Schwarzschild black hole with fixed energy was determined long ago in the form of the Aichelburg-Sexl shockwave, but the status of th…
Snowmass White Paper: the Double Copy and its Applications
Tim Adamo, John Joseph M. Carrasco, Mariana Carrillo-González +6
The double copy is, in essence, a map between scattering amplitudes in a broad variety of familiar field and string theories. In addition to the mathematically rich intrinsic struc…
Classical physics from amplitudes on curved backgrounds
Tim Adamo, Andrea Cristofoli, Anton Ilderton
We generalise the Kosower-Maybee-O'Connell (KMOC) formalism relating classical observables and scattering amplitudes to curved backgrounds. We show how to compute the final semicla…
Graviton scattering in self-dual radiative space-times
Tim Adamo, Lionel Mason, Atul Sharma
The construction of amplitudes on curved space-times is a major challenge, particularly when the background has non-constant curvature. We give formulae for all tree-level graviton…
