Analyticity of the Black Hole S-Matrix
Miguel Correia, Tushar Gopalka, Giulia Isabella +1
We establish the analytic structure of the S-matrix in the complex-frequency plane for classical wave scattering on a Schwarzschild background in four space-time dimensions. Our ar…
The Born regime of gravitational amplitudes
Miguel Correia, Giulia Isabella
We study the scattering in the regime where the wavelength of the scattered objects is comparable to their distance but is much larger than any Compton wavelength in the…
Gravitational Wave Scattering via the Born Series: Scalar Tidal Matching to and Beyond
Simon Caron-Huot, Miguel Correia, Giulia Isabella +1
We introduce a novel method to compute gravitational wave amplitudes within the framework of effective field theory. By reinterpreting the Feynman diagram expansion as a Born serie…
Records from the S-Matrix Marathon: Gravitational Physics from Scattering Amplitudes
Miguel Correia, Holmfridur S. Hannesdottir, Giulia Isabella +5
These lecture notes explain how classical gravitational physics emerges from scattering amplitudes. We emphasize the role of different kinematic regimes in probing various aspects…
