We complete the calculation of conservative two-body scattering dynamics at fourth post-Minkowskian order, i.e., O(G^{4}) and all orders in velocity, including radiative contributions corresponding to the tail effect in general relativity. As in previous calculations, we harness powerful tools from the modern scattering amplitudes program including generalized unitarity, the double copy, and advanced multiloop integration methods, in combination with effective field theory. The classical…

Conservative Binary Dynamics with a Spinning Black Hole at $\mathcal{O}(G^3)$ from Scattering Amplitudes
We compute the conservative two-body Hamiltonian of a compact binary system with a spinning black hole through O ( G 3 ) to all orders in velocity, including linear and quadratic spin terms. To
Scalar QED as a toy model for higher-order effects in classical gravitational scattering
Quantum Electrodynamics (QED) serves as a useful toy model for classical observables in gravitational two-body systems with reduced complexity due to the linearity of QED. We investigate scattering

Searching for Kerr in the 2PM amplitude
: The classical scattering of spinning objects is well described by the spinor-helicity formalism for heavy particles. Using these variables, we derive spurious-pole-free, all-spin opposite-helicity

Momentum recoil in the relativistic two-body problem: Higher-order tails
In the description of the relativistic two-body interaction, together with the effects of energy and angular momentum losses due to the emission of gravitational radiation, one has to take into
Angular momentum of zero-frequency gravitons
By following closely Weinberg’s soft theorem, which captures the 1 /ω pole contribution to the amplitude for soft graviton emissions ( ω < Λ) on top of an arbitrary background hard process, we

: Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in terms of
Multipolar invariants and the eccentricity enhancement function parametrization of gravitational radiation
Gravitational radiation can be decomposed as an infinite sum of radiative multipole moments, which parametrize the waveform at infinity. The multipolar-post-Minkowskian formalism provides a connection

TLDR
There is an abundancy of systems characterized by parabolic PDEs in science and engineering, especially in chemistry and physics, where certain PDE(s), depending on so-called spatial coordinates, govern the behavior of the system in these and similar cases even though the partial differential equation nature is not necessarily needed.
