single-minus superamplitudes and dual superconformal symmetry
Andreas Brandhuber, Paolo Pichini, Gabriele Travaglini +1
We construct the supersymmetric completion of the recently proposed single-minus gluon amplitudes in signature, which are nonvanishing for all multiplicitie…
The Magnus expansion in relativistic quantum field theory
Andreas Brandhuber, Graham R. Brown, Paolo Pichini +2
We investigate the Magnus expansion of the -operator in relativistic quantum field theory, which is related to the -matrix via . We develop direct methods to comp…
Binary Kerr black-hole scattering at 2PM from quantum higher-spin Compton
Lara Bohnenblust, Lucile Cangemi, Henrik Johansson +1
Quantum higher-spin theory applied to Compton amplitudes has proven to be surprisingly useful for elucidating Kerr black hole dynamics. Here we apply the framework to compute scatt…
Searching for Kerr in string amplitudes
Francesco Alessio, Paolo Di Vecchia, Maurizio Firrotta +1
We continue the approach of [1] to attempt to reproduce the classical electromagnetic current of the solution from the infinite-spin limit of a three-point a…
Compton Amplitude for Rotating Black Hole from QFT
Lucile Cangemi, Marco Chiodaroli, Henrik Johansson +3
We construct a candidate tree-level gravitational Compton amplitude for a rotating Kerr black hole, for any quantum spin s=0,1/2,1,...,, from which we extract the correspon…
Spinning binary dynamics in cubic effective field theories of gravity
Andreas Brandhuber, Graham R. Brown, Paolo Pichini +2
We study the binary dynamics of two Kerr black holes with arbitrary spin vectors in the presence of parity-even and parity-odd cubic deformations of gravity. We first derive the tr…
