Twistor formulation of massless 6D infinite spin fields

open access: yesNuclear Physics B, 2021
We construct massless infinite spin irreducible representations of the six-dimensional Poincaré group in the space of fields depending on twistor variables. It is shown that the massless infinite spin representation is realized on the two-twistor fields.

Higher-spin self-dual Yang-Mills and gravity from the twistor space

open access: yesJournal 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 ...

Generalized almost even-Clifford manifolds and their twistor spaces

open access: yesComplex Manifolds, 2021
Motivated by the recent interest in even-Clifford structures and in generalized complex and quaternionic geometries, we introduce the notion of generalized almost even-Clifford structure. We generalize the Arizmendi-Hadfield twistor space construction on

Twistor Actions for Integrable Systems

open access: yesJournal of High Energy Physics, 2021
Many integrable systems can be reformulated as holomorphic vector bundles on twistor space. This is a powerful organizing principle in the theory of integrable systems.

Ambitwistor strings in six and five dimensions

open access: yesJournal of High Energy Physics, 2021
Ambitwistor strings are chiral (holomorphic) strings whose target is the space of complex null geodesics, ambitwistor space. We introduce twistor representations of ambitwistor space in 6 and 5 dimensions.

The celestial chiral algebra of self-dual gravity on Eguchi-Hanson space

open access: yesJournal of High Energy Physics, 2023
We consider the twistor description of classical self-dual Einstein gravity in the presence of a defect operator wrapping a certain ℂℙ1. The backreaction of this defect deforms the flat twistor space to that of Eguchi-Hanson space.

Mini-twistors and the Cotton double copy

open access: yesJournal of High Energy Physics, 2023
The double copy relates quantities in gauge, gravity and related theories. A well-known procedure for relating exact classical solutions is the Weyl double copy in four spacetime dimensions, and a three-dimensional analogue of this — the Cotton double ...

A twistorial description of the IKKT-matrix model

open access: yesJournal of High Energy Physics, 2022
We consider the fuzzy 4-sphere S N 4 $$ {S}_N^4 $$ as a background in the IKKT matrix model, and explore the relation between S N 4 $$ {S}_N^4 $$ and fuzzy twistor space in the semi-classical limit.

Twistor constructions for higher-spin extensions of (self-dual) Yang-Mills

open access: yesJournal of High Energy Physics, 2021
We present the inverse Penrose transform (the map from spacetime to twistor space) for self-dual Yang-Mills (SDYM) and its higher-spin extensions on a flat background.

Alternative formulations of the twistor double copy

open access: yesJournal of High Energy Physics, 2022
The classical double copy relating exact solutions of biadjoint scalar, gauge and gravity theories continues to receive widespread attention. Recently, a derivation of the exact classical double copy was presented, using ideas from twistor theory, in ...
