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…
