On-shell superspace techniques are used to quantify R-symmetry violation in type IIB superstring theory amplitudes in a flat background in ten dimensions. This shows the existence of a particularly simple class of non-vanishing amplitudes in this theory which violate R-symmetry maximally. General properties of the class and some of its extensions are established which at string tree level are shown to determine the first three non-trivial effective field theory contributions to all multiplicity. This leads to a natural conjecture for the exact analytic part of the first two of these.

  1. 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.

  2. On polarized scattering equations for superamplitudes of 11D supergravity and ambitwistor superstring

    hep-th 2019-08 conditional novelty 6.0 of 10

    The polarized scattering equation for 11D supergravity is derived from the supertwistor form of the ambitwistor superstring with SO(16) covariance, and a fermionic superpartner equation on superamplitudes is found.
