We study the scattering of eight gauge fields, and give all the tree-level amplitudes in the helicity-conserved sector. New symmetries are noted, suggesting that significant further simplification can be achieved.

A brief review is given of why twistor geometry has taken a central place in the theory of scattering amplitudes for fundamental particles and the development of which has now led to the definition by Arkani-Hamed et al. of the ‘amplituhedron’.

Applications of Subleading-Color Amplitudes in N = 4 SYM Theory

A number of features and applications of subleading-color amplitudes of N=4 SYM theory are reviewed. Particular attention is given to the IR divergences of the subleading-color amplitudes, the

A first course on twistors, integrability and gluon scattering amplitudes

These notes accompany an introductory lecture course on the twistor approach to supersymmetric gauge theories aimed at early stage PhD students. It was held by the author at the University of

General split helicity gluon tree amplitudes in open twistor string theory

We evaluate all split helicity gluon tree amplitudes in open twistor string theory. We show that these amplitudes satisfy the BCFW recurrence relations restricted to the split helicity case and,

On perturbative field theory and twistor string theory

It is well-known that perturbative calculations in field theory can lead to far simpler answers than the Feynman diagram approach might suggest. In some cases scattering amplitudes can be constructed

Eliminating spurious poles from gauge-theoretic amplitudes

A bstractThis note addresses the problem of spurious poles in gauge-theoretic scattering amplitudes. New twistor coordinates for the momenta are introduced, based on the concept of dual conformal

Scattering amplitudes and BCFW recursion in twistor space

Twistor ideas have led to a number of recent advances in our understanding of scattering amplitudes. Much of this work has been indirect, determining the twistor space support of scattering

The S-matrix in twistor space

The marvelous simplicity and remarkable hidden symmetries recently uncovered in (Super) Yang-Mills and (Super)Gravity scattering amplitudes strongly suggests the existence of a “weak-weak” dual

The tree formula for MHV graviton amplitudes

We present and prove a formula for the MHV scattering amplitude of n gravitons at tree level. Some of the more interesting features of t he formula, which set it apart as being significantly



Twistor diagrams for all tree amplitudes in gauge theory: a helicity-independent formalism

We give a new formalism for pure gauge-theoretic scattering at tree-amplitude level. We first describe a generalization of the Britto-Cachazo-Feng recursion relation in which a significant

Twistor diagram recursion for all gauge-theoretic tree amplitudes

The twistor diagram formalism for scattering amplitudes is introduced, emphasising its finiteness and conformal symmetry. It is shown how MHV amplitudes are simply represented by twistor diagrams.

Amplitude for n-gluon scattering.

A nontrivial squared helicity amplitude is given for the scattering of an arbitrary number of gluons to lowest order in the coupling constant and to leading order in the number of colors.
