abstract

We derive the complete five-gluon scattering amplitude at tree level, within the context of Open Superstring theory. We find the general expression in terms of kinematic factors, and also find its complete expansion up to ${\cal O}({\alpha'}^3)$ terms. We use our scattering amplitude to test three non-equivalent ${\cal O}({\alpha'}^3)$ effective lagrangians that have recently been matter of some controversy.

  1. High-Energy Fixed-Angle Meson Scattering and the Constituent Counting Rule in Holographic QCD

    hep-th 2024-12 conditional novelty 7.0 of 10

    A generalized Polchinski-Strassler ansatz that keeps the extra-dimensional momentum terms restores the constituent counting rule for rho-meson scattering and satisfies the Nambu-Goldstone equivalence theorem.

  2. A field-inspired derivation of open string amplitudes

    hep-th 2026-08 conditional novelty 6.0 of 10

    A perturbiner-like recursion with a weak associativity condition generates multi-parametric series representations of open string tree amplitudes without moduli integration.

  3. Energy correlators in four-dimensional gravity

    hep-th 2025-12 conditional novelty 6.0 of 10

    Gravitational energy correlators in four dimensions are computed at one loop, shown to be infrared-finite, and resummed in the back-to-back limit by soft-graviton exponentiation.

  4. Type IIB at eight derivatives: Five-Point Axio-Dilaton Couplings

    hep-th 2025-07 conditional novelty 6.0 of 10

    The complete five-point, eight-derivative effective action of Type IIB in the gravity plus axio-dilaton sector is derived, with identical tree-level and one-loop kinematics and full SL(2,Z) modular completion.
