Local-in-Time Conservative Binary Dynamics at Fifth Post-Minkowskian and First Self-Force Orders

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

We report the local-in-time conservative dynamics of nonspinning binary systems at fifth Post-Minkowskian (5PM) and first self-force (1SF) orders. This follows from an explicit cal…

Local-in-time Conservative Binary Dynamics at Fourth Post-Minkowskian Order

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

Leveraging scattering information to describe binary systems in generic orbits requires identifying local- and nonlocal-in-time tail effects. We report here the derivation of the u…

Bootstrapping the relativistic two-body problem

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +1

We describe the formalism to compute gravitational-wave observables for compact binaries via the effective field theory framework in combination with modern tools from collider phy…

Radiation Reaction and Gravitational Waves at Fourth Post-Minkowskian Order

Christoph Dlapa, Gregor Kälin, Zhengwen Liu +2

We obtain the total impulse in the scattering of non-spinning binaries in general relativity at fourth Post-Minkowskian order, i.e. , including linear, nonlinear, an…

Machine Learning Post-Minkowskian Integrals

Ryusuke Jinno, Gregor Kälin, Zhengwen Liu +1

We study a neural network framework for the numerical evaluation of Feynman loop integrals that are fundamental building blocks for perturbative computations of physical observable…

Tree-level soft emission of a quark pair in association with a gluon

Vittorio Del Duca, Claude Duhr, Rayan Haindl +1

We compute the tree-level current for the emission of a soft quark-antiquark pair in association with a gluon. This soft current is the last missing ingredient to understand the in…
