Double-copying self-dual Yang-Mills theory to self-dual gravity on twistor space
Journal of High Energy Physics, 2023 We construct a simple Lorentz-invariant action for maximally supersymmetric self-dual Yang-Mills theory that manifests colour-kinematics duality. We also show that this action double-copies to a known action for maximally supersymmetric self-dual gravity.

$L_\infty$-Algebras, the BV Formalism, and Classical Fields [PDF]
, 2019 We summarise some of our recent works on $L_\infty$-algebras and quasi-groups with regard to higher principal bundles and their applications in twistor theory and gauge theory.

Twistor String Theory and QCD [PDF]
Proceedings of International Europhysics Conference on High Energy Physics — PoS(HEP2005), 2007 I review recent progress in using twistor-inspired methods to compute perturbative scattering amplitudes in gauge theory, for application to collider physics.

Dispersionless Hierarchies, Hamilton-Jacobi Theory and Twistor Correspondences
, 1997 The dispersionless KP and Toda hierarchies possess an underlying twistorial structure. A twistorial approach is partly implemented by the method of Riemann-Hilbert problem. This is however still short of clarifying geometric ingredients of twistor theory,

Yangian in the Twistor String [PDF]
, 2010 We study symmetries of the quantized open twistor string. In addition to global PSL(4|4) symmetry, we find non-local conserved currents. The associated non-local charges lead to Ward identities which show that these charges annihilate the string gluon ...

Twistor description of spinning particles in AdS
Journal of High Energy Physics, 2018 The two-twistor formulation of particle mechanics in D-dimensional anti-de Sitter space for D = 4, 5, 7, which linearises invariance under the AdS isometry group Sp(4; K $$ \mathbb{K} $$) for K=ℝ,ℂ,ℍ $$ \mathbb{K}=\mathbb{R},\mathbb{C},\mathrm{\mathbb{H}}

Classical geometry from the tensionless string
Journal of High Energy Physics, 2023 Tensionless string theory on AdS3 × S3 × M $$ \mathcal{M} $$ is explored in the limit that the strings wind the asymptotic boundary a large number of times. Although the worldsheet is usually thought to be localised to the AdS boundary, we argue that the

Higher-point integrands in $\mathcal{N} = 4$ super Yang-Mills theory
SciPost Physics, 2023 We compute the integrands of five-, six-, and seven-point correlation functions of twenty-prime operators with general polarizations at the two-loop order in $\mathcal{N}=4$ super Yang-Mills theory. In addition, we compute the integrand of the five-point

New twistor string theories revisited [PDF]
Physics Letters B, 2009 A gauged version of Berkovits twistor string theory featuring the particle content of N=8 supergravity was suggested by Abou-Zeid, Hull and Mason. The equations of motion for a particular multiplet in the modified theory are examined on the level of basic twistor fields and thereby shown to imply the vanishing of the negative helicity graviton on-shell.
