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.

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.

String scattering amplitudes and deformed cubic string field theory
Physics Letters B, 2018 We study string scattering amplitudes by using the deformed cubic string field theory which is equivalent to the string field theory in the proper-time gauge.

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

Protostring scattering amplitudes
Physical Review D, 2016 We calculate some tree level scattering amplitudes for a generalization of the protostring, which is a novel string model implied by the simplest string bit models. These bit models produce a lightcone worldsheet which supports $s$ integer moded Grassmann fields.

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.

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.

Aspects of supersymmetric field theories in four and six dimensions [PDF]
, 2011 PhDSupersymmetry is an important concept in modern high energy physics. It has found many applications in theoretical considerations of supersymmetric gauge theories as well as in phenomenological approaches to physics beyond the Standard Model.
