Amplitudes at strong coupling as hyperkähler scalars

Hadleigh Frost, Ömer Gürdogan, Lionel Mason

Alday & Maldacena conjectured an equivalence between string amplitudes in AdS and null polygonal Wilson loops in planar super-Yang-Mills (SYM). At st…

Yang-Mills form factors on self-dual backgrounds

Giuseppe Bogna, Lionel Mason

The construction of perturbative quantities on non-linear backgrounds leads to the possibility of incorporating strong field effects in perturbation theory. We continue a programme…

Massive ambitwistor-strings; twistorial models

Giulia Albonico, Yvonne Geyer, Lionel Mason

Ambitwistor-strings are chiral strings whose targets are spaces of complex massless particles, and whose correlation functions directly lead to simple, compact formulae for scatter…

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…
