A key obstruction to the twistor programme has been its so-called ‘googly problem’, unresolved for nearly 40 years, which asks for a twistor description of right-handed interacting massless fields (positive helicity), using the same twistor conventions that give rise to left-handed fields (negative helicity) in the standard ‘nonlinear graviton’ and Ward constructions. An explicit proposal for resolving this obstruction—palatial twistor theory—is put forward (illustrated in the case of… 

Twistor Theory as an Approach to Fundamental Physics

The original motivations underlying the introduction of twistor theory are described, demanding a (3+1)-dimensional space-time theory dependent upon complex analysis and geometry. Space-time points

Lectures on twistor theory

Broadly speaking, twistor theory is a framework for encoding physical information on space-time as geometric data on a complex projective space, known as a twistor space. The relationship between

Twistor theory at fifty: from contour integrals to twistor strings

The Newtonian limit of twistor theory is discussed and its possible role in Penrose’s proposal for a role of gravity in quantum collapse of a wave function is discussed.

Twistor action for general relativity

We reformulate Euclidean general relativity without cosmological constant as an action governing the complex structure of twistor space. Extending Penrose’s non-linear graviton construction, we find

Newtonian Twistor Theory

In twistor theory the nonlinear graviton construction realises four-dimensional anti-self-dual Ricci-flat manifolds as Kodaira moduli spaces of rational curves in three-dimensional complex manifolds.

Celestial w1+∞ Symmetries from Twistor Space

. We explain how twistor theory represents the self-dual sector of four dimensional gravity in terms of the loop group of Poisson diffeomorphisms of the plane via Penrose’s nonlinear graviton

Palatial Twistors from Quantum Inhomogeneous Conformal Symmetries and Twistorial DSR Algebras

The recently introduced palatial NC twistors are constructed by considering the pair of conjugated (Born-dual) twist-deformed D=4 quantum inhomogeneous conformal Hopf algebras and the quantum deformations of Heisenberg-conformal algebra (HCA) su(2,2)⋉T4,4 are introduced providing in twistorial framework the basic covariant quantum elementary system.

Twistor sigma models for quaternionic geometry and graviton scattering

We reformulate the twistor construction for hyperand quaternion-Kähler manifolds, introducing new sigma models that compute scalar potentials for the geometry. These sigma models have the twistor

Symplectic Measures of Contact with Noether

Witten’s covariant symplectic formalism is used to compare a set of cohomologous chiral first-order Lagrangians for gravity through their symplectic structures and thus Liouville/GHS measures that

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’.

Twistor quantisation and curved space-time

AbstractThe formalism of twistors [the ‘spinors’ for the group O(2,4)] is employed to give a concise expression for the solution of the zero rest-mass field equations, for each spin (s=0, 1/2, 1,

It is shown that self-dual solutions of Einstein's equations, with cosmological constant λ, correspond to certain complex manifolds. This result generalizes the work of Penrose [1], who dealt with
