Super-Hawking Radiation
Ricardo Z. Ferreira, Carlo Heissenberg
We discuss modifications to the Hawking spectrum that arise when the asymptotic states are supertranslated or superrotated. For supertranslations we find nontrivial off-diagonal ph…
On asymptotic symmetries in higher dimensions for any spin
Andrea Campoleoni, Dario Francia, Carlo Heissenberg
We investigate asymptotic symmetries in flat backgrounds of dimension higher than or equal to four. For spin two we provide the counterpart of the extended BMS transformations foun…
Universality of ultra-relativistic gravitational scattering
Paolo Di Vecchia, Carlo Heissenberg, Rodolfo Russo +1
We discuss the ultra-relativistic gravitational scattering of two massive particles at two-loop (3PM) level. We find that in this limit the real part of the eikonal, determining th…
Second-order Post-Minkowskian scattering in arbitrary dimensions
Andrea Cristofoli, Poul H. Damgaard, Paolo Di Vecchia +1
We extract the long-range gravitational potential between two scalar particles with arbitrary masses from the two-to-two elastic scattering amplitude at 2nd Post-Minkowskian order…
