Conservative Binary Dynamics with a Spinning Black Hole at O(G^{3}) from Scattering Amplitudes. [PDF]
Physical Review Letters, 2022 We compute the conservative two-body Hamiltonian of a compact binary system with a spinning black hole through O(G^{3}) to all orders in velocity, including linear and quadratic spin terms.

The SAGEX review on scattering amplitudes Chapter 13: Post-Minkowskian expansion from scattering amplitudes [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 The post-Minkowskian expansion of Einstein’s general theory of relativity has received much attention in recent years due to the possibility of harnessing the computational power of modern amplitude calculations in such a classical context. In this brief

The SAGEX review on scattering amplitudes Chapter 8: Half BPS correlators [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 Half BPS correlators in N=4 super Yang–Mills theory are key quantities both in the AdS/CFT correspondence as well as in scattering amplitudes research. They are dual at strong coupling to quantum gravity amplitudes.

Scattering Amplitudes, the Tail Effect, and Conservative Binary Dynamics at O(G^{4}). [PDF]
Physical Review Letters, 2021 We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e., O(G^{4}) and all orders in velocity, including radiative contributions corresponding to the tail effect in general relativity. As in previous

Supergravity scattering amplitudes
Physical Review D, 2023 Supergravity theories with non-minimal Kähler potentials are characterized by a non-trivial field space manifold with corresponding non-trivial kinetic terms. The scattering amplitudes in these theories can be calculated at fixed background field values by making a field redefinition to Riemann normal coordinates.

All Order Gravitational Waveforms from Scattering Amplitudes. [PDF]
Physical Review Letters, 2022 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 order in the post-Newtonian or post-Minkowskian approximation.

Massive color-kinematics duality and double-copy for Kaluza-Klein scattering amplitudes
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 ...
