Type IIB at eight derivatives: insights from Superstrings, Superfields and Superparticles
Abstract We study the non-linear structure of Type IIB eight-derivative couplings involving the metric and the complexified three-form G 3. We show that, at the level of five-point string amplitudes, the kinematics in the maximally R-symmetry-violating sector is fully matched by standard superspace...

| description | Abstract We study the non-linear structure of Type IIB eight-derivative couplings involving the metric and the complexified three-form G 3. We show that, at the level of five-point string amplitudes, the kinematics in the maximally R-symmetry-violating sector is fully matched by standard superspace integrals and by superparticle amplitudes in M-theory on a two-torus. The latter approach is used to determine the complete effective action in this sector and to verify its invariance under SL(2, ℤ) duality. We further comment on the general structure of the higher-point kinematics. Compactifications to lower dimensions provide both tests for our results and the arena for their applications. We verify that K3 reductions are fully consistent with the constraints of six-dimensional supersymmetry, and derive the four-dimensional flux scalar potential and axion kinetic terms at order (α′)3 in Calabi-Yau threefold reductions. |
