Analytical Time-Domain Waveforms for Black-Hole Scattering in the Self-Force Expansion
Chris Kavanagh, Julio Parra-Martinez, Davide Usseglio
We obtain a systematic understanding of the time-domain gravitational waveform of hyperbolic black-hole scattering at first order in the self-force expansion and all orders in the…
Radiated Energy Spectrum, Radiated Angular Distribution and Non-linear Memory from the One-loop Gravitational Bremsstrahlung Waveform
Donato Bini, Thibault Damour, Stefano De Angelis +1
The frequency-domain gravitational waveform emitted by the scattering of two non-spinning massive particles has recently been derived at next-to-leading, \textit{i.e.} one-loop, po…
Weak-field waveforms for generic relativistic orbits
Stefano De Angelis
We recast Einstein's equations as ordinary integro-differential equations for the worldlines, integrating out the gravitational field by means of the Schwinger-Keldysh path integra…
Analytic One-loop Scattering Waveform in General Relativity
Giacomo Brunello, Stefano De Angelis, David A. Kosower
Leveraging the computational framework presented in reference [JHEP 07, 062 (2024)], we evaluate the analytic scattering waveform in General Relativity to second order, $G^3 M^3 /r…
Continuous-Spin Particles, On Shell
Brando Bellazzini, Stefano De Angelis, Marcello Romano
We study on-shell scattering amplitudes for continuous-spin particles (CSPs). Poincaré invariance, little-group covariance, analyticity, and on-shell factorisation (unitar…
An Improved Framework for Computing Waveforms
Giacomo Brunello, Stefano De Angelis
We combine the observable-based formalism (KMOC), the analytic properties of the scattering amplitude, generalised unitarity and the heavy-mass expansion with a newly introduced IB…
Gravitational Waveform: A Tale of Two Formalisms
Donato Bini, Thibault Damour, Stefano De Angelis +4
We revisit the quantum-amplitude-based derivation of the gravitational waveform emitted by the scattering of two spinless massive bodies at the third order in Newton's constant, $h…
Spinning waveforms from KMOC at leading order
Stefano De Angelis, Riccardo Gonzo, Pavel P. Novichkov
We provide the analytic waveform in time domain for the scattering of two Kerr black holes at leading order in the post-Minkowskian expansion and up to fourth order in both spins.…
EFT matching from analyticity and unitarity
Stefano De Angelis, Gauthier Durieux
We present a new on-shell method for the matching of ultraviolet models featuring massive states onto their massless effective field theory. We employ a dispersion relation in the…
One-loop Gravitational Bremsstrahlung and Waveforms from a Heavy-Mass Effective Field Theory
Andreas Brandhuber, Graham R. Brown, Gang Chen +3
Using a heavy-mass effective field theory (HEFT), we study gravitational-wave emission in the scattering of two spinless black holes or neutron stars of arbitrary masses at next-to…
Radiation, entanglement and islands from a boundary local quench
Lorenzo Bianchi, Stefano De Angelis, Marco Meineri
We study the entanglement and the energy density of the radiation emitted after a local quench in a boundary conformal field theory. We use the operator product expansion (OPE) to…
Amplitude bases in generic EFTs
Stefano De Angelis
We present for the first time an efficient algorithm to find a basis of kinematically independent structures built of (massless and massive) spinor helicity variables in four dimen…
Standard Model EFTs via On-Shell Methods
Manuel Accettulli Huber, Stefano De Angelis
We present the Standard Model Effective Field Theories (SMEFT) from purely on-shell arguments. Starting from a few basic assumptions such as Poincaré invariance and locality, we cl…
