Gravitational Bremsstrahlung in the Post-Minkowskian Effective Field Theory
Stavros Mougiakakos, Massimiliano Maria Riva, Filippo Vernizzi
We study the gravitational radiation emitted during the scattering of two spinless bodies in the post-Minkowskian Effective Field Theory approach. We derive the conserved stress-en…

The Schwarzschild-Tangherlini metric from scattering amplitudes in various dimensions
Stavros Mougiakakos, Pierre Vanhove
We derive the static Schwarzschild-Tangherlini metric by extracting the classical contributions from the multi-loop vertex functions of a graviton emitted from a massive scalar fie…

Gravitational cubic-in-spin interaction at the next-to-leading post-Newtonian order
Michèle Levi, Stavros Mougiakakos, Mariana Vieira
In this work we derive for the first time the complete gravitational cubic-in-spin effective action at the next-to-leading order in the post-Newtonian (PN) expansion for the intera…
