Conformal Supergravity in Twistor-String Theory [PDF]
, 2004 Conformal supergravity arises in presently known formulations of twistor-string theory either via closed strings or via gauge-singlet open strings. We explore this sector of twistor-string theory, relating the relevant string modes to the particles and ...

Conformal higher spin theory and twistor space actions [PDF]
, 2016 We consider the twistor description of conformal higher spin theories and give twistor space actions for the self-dual sector of theories with spin greater than two that produce the correct flat space-time spectrum.

Twistor Theory of Dancing Paths
Symmetry, Integrability and Geometry: Methods and Applications, 2022 Given a path geometry on a surface $\mathcal{U}$, we construct a causal structure on a four-manifold which is the configuration space of non-incident pairs (point, path) on $\mathcal{U}$. This causal structure corresponds to a conformal structure if and only if $\mathcal{U}$ is a real projective plane, and the paths are lines.

Superspace Formulation of 4D Higher Spin Gauge Theory [PDF]
, 2002 Interacting AdS_4 higher spin gauge theories with N \geq 1 supersymmetry so far have been formulated as constrained systems of differential forms living in a twistor extension of 4D spacetime.

Twistor theory for co-CR quaternionic manifolds and related structures [PDF]
, 2011 In a general and non-metrical framework, we introduce the class of co-CR quaternionic manifolds, which contains the class of quaternionic manifolds, whilst in dimension three it particularizes to give the Einstein-Weyl spaces.

Heterotic twistor–string theory
Nuclear Physics B, 2008 We reformulate twistor-string theory as a heterotic string based on a twisted (0,2) model. The path integral localizes on holomorphic maps, while the (0,2) moduli naturally correspond to the states of N=4 super Yang-Mills and conformal supergravity under the Penrose transform. We show how the standard twistor-string formulae of scattering amplitudes as

International Journal of Mathematics and Mathematical Sciences, 1986 We describe briefly the basic ideas and results of the twistor theory. The main points: twistor representation of Minkowsky space, Penrose correspondence and its geometrical properties, twistor interpretation of linear massless fields, Yang-Mills fields (

The momentum amplituhedron of SYM and ABJM from twistor-string maps
Journal of High Energy Physics, 2022 We study remarkable connections between twistor-string formulas for tree amplitudes in N $$ \mathcal{N} $$ = 4 SYM and N $$ \mathcal{N} $$ = 6 ABJM, and the corresponding momentum amplituhedron in the kinematic space of D = 4 and D = 3, respectively ...

The S-Matrix in Twistor Space [PDF]
, 2009 The simplicity and hidden symmetries of (Super) Yang-Mills and (Super)Gravity scattering amplitudes suggest the existence of a "weak-weak" dual formulation in which these structures are made manifest at the expense of manifest locality.

Split-quaternionic Hopf map, quantum Hall effect, and twistor theory [PDF]
, 2009 Introducing a noncompact version of the Hopf map, we demonstrate remarkable close relations between quantum Hall effect and twistor theory. We first construct quantum Hall effect on a hyperboloid based on the noncompact 2nd Hopf map of split-quaternions.
