MHV diagrams give an efficient Feynman diagram-like formalism for calculating gauge theory scattering amplitudes on momentum space. Although they arise as the Feynman diagrams from an action on twistor space in an axial gauge, the main ingredients were previously expressed only in momentum space and momentum twistor space. Here we show how the formalism can be elegantly derived and expressed entirely in twistor space. This brings out the underlying superconformal invariance of the framework (up… 

On form factors and correlation functions in twistor space

A bstractIn this paper, we continue our study of form factors and correlation functions of gauge-invariant local composite operators in the twistor-space formulation of N=4$$ \mathcal{N}=4 $$ super

From d logs to dilogs; the super Yang-Mills MHV amplitude revisited

A bstractRecently, loop integrands for certain Yang-Mills scattering amplitudes and correlation functions have been shown to be systematically expressible in d log form, raising the possibility that

Twistor actions for gauge theory and gravity

This is a review of recent developments in the study of perturbative gauge theory and gravity using action functionals on twistor space. It is intended to provide a user-friendly introduction to

Gluon scattering on self-dual radiative gauge fields

We present all-multiplicity formulae for the tree-level S-matrix of gluons in self-dual radiative backgrounds, which are chiral, asymptotically flat gauge fields characterised by their free radiative

Form factors and correlation functions in N = 4 super Yang-Mills theory from twistor space

TLDR
The twistor formalism is extended to encompass (partially) off-shell quantities and is used to compute form factors at NMHV and higher NkMHV level in parallel to how this had been done for amplitudes previously.

On Twistors and Conformal Field Theories from Six Dimensions

We discuss chiral zero-rest-mass field equations on six-dimensional space-time from a twistorial point of view. Specifically, we present a detailed cohomological analysis, develop both Penrose and

From the holomorphic Wilson loop to ‘d log’ loop-integrands of super-Yang-Mills amplitudes

A bstractThe S-matrix for planar $ \mathcal{N} $ = 4 super Yang-Mills theory can be computed as the correlation function for a holomorphic polygonal Wilson loop in twistor space. In an axial gauge,

Composite Operators in the Twistor Formulation of N=4 Supersymmetric Yang-Mills Theory.

TLDR
This Letter incorporates gauge-invariant local composite operators into the twistor-space formulation of N=4 super Yang-Mills theory, and uses the composite operator built from two identical complex scalars as a pedagogical example.

Dual superconformal invariance has recently emerged as a hidden symmetry of planar scattering amplitudes in = 4 super Yang-Mills theory. This symmetry can be made manifest by expressing amplitudes in
