Gravity from holomorphic discs and celestial symmetries
Lionel Mason
In split or Kleinian signature, twistor constructions parametrize solutions to both gauge and gravity self-duality (SD) equation from twistor data that can be expressed in terms of…
The SAGEX Review on Scattering Amplitudes, Chapter 6: Ambitwistor Strings and Amplitudes from the Worldsheet
Yvonne Geyer, Lionel Mason
Starting with Witten's twistor string, chiral string theories have emerged that describe field theory amplitudes without the towers of massive states of conventional strings. These…
The SAGEX Review on Scattering Amplitudes
Gabriele Travaglini, Andreas Brandhuber, Patrick Dorey +35
This is an introduction to, and invitation to read, a series of review articles on scattering amplitudes in gauge theory, gravity, and superstring theory. Our aim is to provide an…
From Twistor-Particle Models to Massive Amplitudes
Giulia Albonico, Yvonne Geyer, Lionel Mason
In his twistor-particle programme of the 1970's, Roger Penrose introduced a representation of the massive particle phase space in terms of a pair of twistors subject to an internal…
Graviton scattering in self-dual radiative space-times
Tim Adamo, Lionel Mason, Atul Sharma
The construction of amplitudes on curved space-times is a major challenge, particularly when the background has non-constant curvature. We give formulae for all tree-level graviton…
