In this letter, an alternative string theory in twistor space is proposed for describing perturbative N=4 super-Yang-Mills theory. Like the recent proposal of Witten, this string theory uses twistor worldsheet variables and has manifest spacetime superconformal invariance. However, in this proposal, tree-level super-Yang-Mills amplitudes come from open string tree amplitudes as opposed to coming from D-instanton contributions.

  1. Worldline Higher Spin Gravity

    hep-th 2026-05 unverdicted novelty 8.0 of 10

    A worldline path integral model for higher-spin gravity in AdS4 is constructed using twistor actions and double-line vertices, reproducing boundary correlators of free boson and fermion vector models.

  2. 4d CFT Correlators from Ambitwistors

    hep-th 2026-06 conditional novelty 7.0 of 10

    Conserved spinning two- and three-point correlators in 4d CFTs are obtained from holomorphic contour integrals on ambitwistor space, with spin, parity, and even a conformally coupled scalar treated uniformly.

  3. The spectrum of the bosonic ambitwistor string revisited

    hep-th 2026-06 unverdicted novelty 5.0 of 10

    The bosonic ambitwistor string spectrum is confined to the massless sector and contains the dilaton, metric, Kalb-Ramond field plus an extra vector, but is non-unitary.

  4. Remarks on Associated Varieties and Minimal Tension Holography

    hep-th 2025-07 conditional novelty 5.0 of 10

    The associated variety of the psl(2|2) vertex algebra is identified with the cotangent bundle of the twistor space of the AdS3 boundary, and a new quotient-free free field realization of V1(psl(4|4)) is written down.

  5. Celestial Chiral Algebras and Self-Dual Gravity

    hep-th 2025-07 conditional novelty 4.0 of 10

    This thesis derives deformations of celestial chiral algebras in self-dual gravity on curved backgrounds, obtaining W(infinity) on Eguchi-Hanson space, Ldiff_q(C) under Moyal deformation, and a two-parameter deformati...

    hep-th 2025-06 reject novelty 4.0 of 10

    A topological A-model from CP^{3|4} supertwistors is claimed to reproduce the 't Hooft expansion of N=4 SYM and is related to the pure spinor AdS5×S5 superstring.
