Plahte diagrams for string scattering amplitudes

Journal of High Energy Physics, 2021
Plahte identities are monodromy relations between open string scattering amplitudes at tree level derived from the Koba-Nielsen formula. We represent these identities by polygons in the complex plane.

Tree-Level Formalism [PDF]

, 2011
We review two novel techniques used to calculate tree-level scattering amplitudes efficiently: MHV diagrams, and on-shell recursion relations. For the MHV diagrams, we consider applications to tree-level amplitudes and focus in particular on the N=4 ...

ABJM flux-tube and scattering amplitudes

Journal of High Energy Physics, 2019
There is a number of indications that scattering amplitudes in the Aharony-Bergman-Jafferis-Maldacena theory might have a dual description in terms of a holonomy of a supergauge connection on a null polygonal contour in a way analogous to the four ...

The Interacting $W_3$ String [PDF]

, 1993
We present a procedure for computing gauge-invariant scattering amplitudes in the $W_3$ string, and use it to calculate three-point and four-point functions.

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

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.

Scattering amplitudes and contour deformations [PDF]

Physical Review D, 2019
We employ a scalar model to exemplify the use of contour deformations when solving Lorentz-invariant integral equations for scattering amplitudes. In particular, we calculate the onshell 2 -> 2 scattering amplitude for the scalar system. The integrals produce branch cuts in the complex plane of the integrand which prohibit a naive Euclidean ...

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 ...

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
