The KLT Kernel in Twistor Space. [PDF]
Commun Math PhysThe double copy relationship between Yang–Mills theory and general relativity can be stated in terms of a field theory Kawai–Lewellen–Tye (KLT) momentum kernel, which maps two colour-ordered gluon amplitudes to a graviton amplitude at tree-level.

Twistor space origins of the Newman-Penrose map [PDF]
SciPost Physics, 2022 Recently, we introduced the "Newman-Penrose map", a novel correspondence between a certain class of solutions of Einstein's equations and self-dual solutions of the vacuum Maxwell equations, which we showed was closely related to the classical double ...

Higher-spin self-dual Yang-Mills and gravity from the twistor space [PDF]
Journal of High Energy Physics, 2023 We lift the recently proposed theories of higher-spin self-dual Yang-Mills (SDYM) and gravity (SDGR) to the twistor space. We find that the most natural room for their twistor formulation is not in the projective, but in the full twistor space, which is ...

Integrable deformations from twistor space [PDF]
SciPost Physics, 2023 Integrable field theories in two dimensions are known to originate as defect theories of 4d Chern-Simons and as symmetry reductions of the 4d anti-self-dual Yang-Mills equations.

The Weyl double copy from twistor space [PDF]
Journal of High Energy Physics, 2021 The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar, gauge and gravity theories, and relates fields in spacetime directly.

Scattering amplitudes and Wilson loops in twistor space [PDF]
, 2011 This paper reviews the recent progress in twistor approaches to Wilson loops, amplitudes and their duality for super-Yang–Mills. Wilson loops and amplitudes are derived from first principles using the twistor action for maximally supersymmetric Yang ...

The S-matrix in twistor space [PDF]
, 2009 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 formulation of these theories where these structures are ...

Conformal higher spin scattering amplitudes from twistor space [PDF]
Journal of High Energy Physics, 2017 We use the formulation of conformal higher spin (CHS) theories in twistor space to study their tree-level scattering amplitudes, finding expressions for all three-point M H V ¯ $$ \overline{\mathrm{MHV}} $$ amplitudes and all MHV amplitudes involving ...

Twistor Space for Rolling Bodies [PDF]
, 2012 On a natural circle bundle $${\mathbb{T}(M)}$$T(M) over a 4-dimensional manifold M equipped with a split signature metric g, whose fibers are real totally null selfdual 2-planes, we consider a tautological rank 2 distribution $${\mathcal{D}}$$D obtained ...
