The Magnus expansion in relativistic quantum field theory

Andreas Brandhuber, Graham R. Brown, Paolo Pichini +2

We investigate the Magnus expansion of the $N$ -operator in relativistic quantum field theory, which is related to the $S$ -matrix via $S = e^{i N}$ . We develop direct methods to comp…

Spinning quadrupoles in effective field theories of gravity

Andreas Brandhuber, Graham R. Brown, Gabriele Travaglini +1

We study the effect of the two independent parity-even cubic interactions $I_{1} = R^{α β}_{μν} R^{μν}_{ρ σ} R^{ρ σ}_{α β}$ and $G_{3} = I_{1} - 2 R^{μν α}_{β} R^{β γ}_{ν σ} R^{σ}_{μ γ α}$ …

Spinning waveforms in cubic effective field theories of gravity

Andreas Brandhuber, Graham R. Brown, Gang Chen +2

We derive analytic all-order-in-spin expressions for the leading-order time-domain waveforms generated in the scattering of two Kerr black holes with arbitrary masses and spin vect…

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…
