Classical gravitational spinning-spinless scattering at
Rafael Aoude, Kays Haddad, Andreas Helset
Making use of the recently-derived, all-spin, opposite-helicity Compton amplitude, we calculate the classical gravitational scattering amplitude for one spinning and one spinless o…

Searching for Kerr in the 2PM amplitude
Rafael Aoude, Kays Haddad, Andreas Helset
The classical scattering of spinning objects is well described by the spinor-helicity formalism for heavy particles. Using these variables, we derive spurious-pole-free, all-spin o…
