The classical double copy relates exact solutions of gauge, gravity and other theories. Although widely studied, its origins and domain of applicability have remained mysterious. In this letter, we show that a particular incarnation - the Weyl double copy - can be derived using well-established ideas from twistor theory. As well as explaining where the Weyl double copy comes from, the twistor formalism also shows that it is more general than previously thought.

  1. Mass/electric versus NUT/magnetic charges: duality from scattering amplitudes in $D\geq4$ and for all bosonic spins

    hep-th 2026-07 conditional novelty 7.0

    Kerr-NUT mass/electric and equal-NUT/magnetic charges are dual in D≥4, realized as J_σ ↔ J_−σ in 3-point amplitudes generated by a spin-raising operator for all bosonic spins.

  2. 4d CFT Correlators from Ambitwistors

    hep-th 2026-06 conditional novelty 7.0

    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. Untwisting the double copy: the zeroth copy as an optical seed

    hep-th 2026-04 unverdicted novelty 7.0

    A single complex optical seed built from expansion and twist organizes stationary Kerr-Schild geometries, reconstructs the congruence, and encodes the zeroth-copy data that generates both the gravitational profile and...

  4. Non-topological solitons in biadjoint scalar field theory

    hep-th 2026-06 unverdicted novelty 6.0

    Biadjoint scalar theory admits a family of non-topological solitons carrying U(1) charge, time-dependent like Q-balls, stable in truncation, with finite localized energy.

  5. Graviton Photoproduction by a Kerr-Newman Black Hole with Worldline EFT

    hep-th 2026-01 conditional novelty 6.0

    The graviton-to-photon conversion amplitude for a Kerr-Newman black hole is computed through O(S^2) in the long-wavelength worldline EFT and shown to be fully determined by the black hole's electromagnetic and mass mu...

  6. The Penrose Transform and the Kerr-Schild double copy

    hep-th 2025-11 unverdicted novelty 6.0

    The Kerr-Schild and twistorial double copies are equivalent for self-dual vacuum Kerr-Schild spacetimes.

  7. Hawking Radiation meets the Double Copy

    hep-th 2025-10 unverdicted novelty 6.0

    Bogoliubov coefficients from scattering a scalar in a collapsing EM background (single copy of Vaidya) match ray-tracing results and connect to Hawking radiation through the double copy.

  8. Spin versus Magic: Lessons from Gluon and Graviton Scattering

    hep-th 2025-08 accept novelty 6.0

    For 2 to 2 scattering of massless spin-1/2 to spin-2 particles, the averaged generated magic decreases monotonically with spin, with maxima well below the two-qubit upper bound.
