Massive color-kinematics duality and double-copy for Kaluza-Klein scattering amplitudes [PDF]
Journal of High Energy Physics, 2023 We study the structure of scattering amplitudes of massive Kaluza-Klein (KK) states under toroidal compactification. We present a shifting method to quantitatively derive the scattering amplitudes of massive KK gauge bosons and KK gravitons from the ...

The sub-leading scattering waveform from amplitudes [PDF]
Journal of High Energy Physics, 2023 We compute the next-to-leading order term in the scattering waveform of uncharged black holes in classical general relativity and of half-BPS black holes in N $$ \mathcal{N} $$ = 8 supergravity.

Post-Newtonian waveforms from spinning scattering amplitudes [PDF]
Journal of High Energy Physics, 2022 We derive the classical gravitational radiation from an aligned spin binary black hole on closed orbits, using a dictionary built from the 5-point QFT scattering amplitude of two massive particles exchanging and emitting a graviton.

Soft radiation from scattering amplitudes revisited [PDF]
Journal of High Energy Physics, 2021 We apply the recently developed formalism by Kosower, Maybee and O’Connell (KMOC) [12] to analyse the soft electromagnetic and soft gravitational radiation emitted by particles without spin in D ≥ 4 dimensions.

Gravitational shock waves and scattering amplitudes [PDF]
Journal of High Energy Physics, 2020 We study gravitational shock waves using scattering amplitude techniques. After first reviewing the derivation in General Relativity as an ultrarelativistic boost of a Schwarzschild solution, we provide an alternative derivation by exploiting a novel ...

Splitting CEGM amplitudes [PDF]
Journal of High Energy PhysicsThe CEGM formalism offers a general framework for scattering amplitudes, which rests on Grassmannians, moduli spaces and tropical geometry. The physical implications of this generalization are still to be understood.

Scattering amplitudes for self-force [PDF]
Classical and quantum gravity, 2023 The self-force expansion allows the study of deviations from geodesic motion due to the emission of radiation and its consequent back-reaction. We investigate this scheme within the on-shell framework of semiclassical scattering amplitudes for particles ...

Scattering Amplitudes: Celestial and Carrollian. [PDF]
Physical Review Letters, 2022 Recent attempts at the construction of holography for asymptotically flat spacetime have taken two different routes. Celestial holography, involving a two dimensional (2D) conformal field theory (CFT) dual to 4D Minkowski spacetime, has generated novel ...

The SAGEX review on scattering amplitudes [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an overview of the field, from basic aspects to a selection of current (2022)
