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…

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…
