Automating scattering amplitudes with chirality flow
European Physical Journal C: Particles and Fields, 2022 Recently we introduced the chirality-flow formalism, a method which builds on the spinor-helicity formalism and is inspired by the color-flow idea in QCD.

Massive on-shell supersymmetric scattering amplitudes
Journal of High Energy Physics, 2019 We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism.

Weights and recursion relations for ϕ p tree amplitudes from the positive geometry
Journal of High Energy Physics, 2020 Recently, the accordiohedron in kinematic space was proposed as the positive geometry for planar tree-level scattering amplitudes in the ϕ p theory [1]. The scattering amplitudes are given as a weighted sum over canonical forms of some accordiohedra with

M5-brane and D-brane scattering amplitudes
Journal of High Energy Physics, 2017 We present tree-level n-particle on-shell scattering amplitudes of various brane theories with 16 conserved supercharges. These include the world-volume theory of a probe D3-brane or D5-brane in 10D Minkowski spacetime as well as a probe M5-brane in 11D ...

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 ...

Four-gauge-particle scattering amplitudes and Polyakov string path integral in the proper-time gauge
Physics Letters B, 2019 We evaluate four-gauge-particle tree level scattering amplitudes using the Polyakov string path integral in the proper-time gauge, where the string path integral can be cast into the Feynman-Schwinger proper-time representation.

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.

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

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 ...

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 ...
