Post-Newtonian waveforms from spinning scattering amplitudes
Journal of High Energy Physics, 2022 We derive the classical gravitational radiation from an aligned spin binary black hole on closed orbits, using a dictionary built from the 5-point QFT scattering amplitude of two massive particles exchanging and emitting a graviton.

Gravitational partial-wave absorption from scattering amplitudes
Journal of High Energy Physics, 2023 We study gravitational absorption effects using effective on-shell scattering amplitudes. We develop an in-in probability-based framework involving plane- and partial-wave coherent states for the incoming wave to describe the interaction of the wave with

Automated computation of scattering amplitudes
, 2013 We review some of the recent advances in the computation of one-loop scattering amplitudes which led to the construction of efficient and automated computational tools for NLO predictions.

The sub-leading scattering waveform from amplitudes
Journal of High Energy Physics, 2023 We compute the next-to-leading order term in the scattering waveform of uncharged black holes in classical general relativity and of half-BPS black holes in N $$ \mathcal{N} $$ = 8 supergravity.

On scattering off the extreme Reissner-Nordstr\"om black hole in N=2 supergravity [PDF]
, 1997 The scattering amplitudes for the perturbed fields of the N=2 supergravity about the extreme Reissner-Nordstr\"om black hole is examined. Owing to the fact that the extreme hole is a BPS state of the theory and preserves an unbroken global supersymmetry ...

Crossing beyond scattering amplitudes
Journal of High Energy PhysicsWe find that different asymptotic measurements in quantum field theory can be related to one another through new versions of crossing symmetry. Assuming analyticity, we conjecture generalized crossing relations for multi-particle processes and the ...

Loop Amplitudes and Quantum Homotopy Algebras
Journal of High Energy Physics, 2020 We derive a recursion relation for loop-level scattering amplitudes of La- grangian field theories that generalises the tree-level Berends-Giele recursion relation in Yang-Mills theory.

Superstring Scattering from D-Branes
, 1996 We derive fully covariant expressions for all two-point scattering amplitudes of two massless closed strings from a Dirichlet $p$-brane. This construction relies on the observation that there is a simple relation between these D-brane amplitudes in type ...

MHV Vertices And Tree Amplitudes In Gauge Theory [PDF]
, 2004 As an alternative to the usual Feynman graphs, tree amplitudes in Yang-Mills theory can be constructed from tree graphs in which the vertices are tree level MHV scattering amplitudes, continued off shell in a particular fashion.

SNUPN‐Related Muscular Dystrophy: Novel Phenotypic, Pathological and Functional Protein Insights
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective SNUPN‐related muscular dystrophy or LGMDR29 is a new entity that covers from a congenital or childhood onset pure muscular dystrophy to more complex phenotypes combining neurodevelopmental features, cataracts, or spinocerebellar ataxia. So far, 12 different variants have been described.
