Resummed spinning waveforms from five-point amplitudes
Andreas Brandhuber, Graham R. Brown, Gang Chen +2
We compute the classical tree-level five-point amplitude for the two-to-two scattering of spinning celestial objects with the emission of a graviton. Using this five-point amplitud…
Self-Dual Fields on Self-Dual Backgrounds and the Double Copy
Graham R. Brown, Joshua Gowdy, Bill Spence
We explore the double copy for self-dual gauge and gravitational fields on self-dual background spacetimes. We consider backgrounds associated to solutions of the second Plebanski…
One-loop Gravitational Bremsstrahlung and Waveforms from a Heavy-Mass Effective Field Theory
Andreas Brandhuber, Graham R. Brown, Gang Chen +3
Using a heavy-mass effective field theory (HEFT), we study gravitational-wave emission in the scattering of two spinless black holes or neutron stars of arbitrary masses at next-to…
Celestial Twistor Amplitudes
Graham R. Brown, Joshua Gowdy, Bill Spence
We show how to formulate celestial twistor amplitudes in Yang-Mills (YM) and gravity. This is motivated by a refined holographic correspondence between the twistor transform and th…
Amplitudes, Hopf algebras and the colour-kinematics duality
Andreas Brandhuber, Graham R. Brown, Gang Chen +3
It was recently proposed that the kinematic algebra featuring in the colour-kinematics duality for scattering amplitudes in heavy-mass effective field theory (HEFT) and Yang-Mills…
Celestial Superamplitudes
Andreas Brandhuber, Graham R. Brown, Joshua Gowdy +2
We study celestial amplitudes in (super) Yang-Mills theory using a parameterisation of the spinor helicity variables where their overall phase is not fixed by the little group acti…
