abstract

Some time ago the bosonic and fermionic 4-field terms of the non-abelian low energy effective action of the open superstring were obtained, to all order in $\alpha'$. This was done at tree level by directly generalizing the abelian case, treated some time before, and considering the known expressions of all massless superstring 4-point amplitudes (at tree level). In the present work we obtain the bosonic 5-field terms of this effective action, to all order in $\alpha'$. This is done by considering the simplified expression of the superstring 5-point amplitude for massless bosons, obtained some time ago.

  1. One-loop open-string integrals from differential equations: all-order alpha'-expansions at n points

    hep-th 2019-08 conditional novelty 8.0 of 10

    A-cycle integrals at genus one satisfy linear differential equations whose Picard iterations yield all-order alpha-prime expansions in iterated Eisenstein integrals, with cusp values given by disk integrals.

  2. 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.

  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.
