Graviton scattering on self-dual black holes
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
The computation of gravitational wave scattering on black hole spacetimes is an extremely hard problem, typically requiring approximation schemes that either treat the black hole p…
From AdS correlators to Carrollian amplitudes with the scattering equation
Tim Adamo, Iustin Surubaru, Bin Zhu
The scattering equations relate massless scattering kinematics to marked points on a Riemann sphere, and underpin remarkable formulae for the full tree-level S-matrices of many int…
Twistorial chiral algebras in higher dimensions
Tim Adamo, Iustin Surubaru
In four spacetime dimensions, the classically integrable self-dual sectors of gauge theory and gravity have associated chiral algebras, which emerge naturally from their descriptio…
Scattering on self-dual Taub-NUT
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
We derive exact solutions of massless free field equations and tree-level two-point amplitudes up to spin 2 on self-dual Taub-NUT space-time, as well as on its single copy, the sel…
