abstract

Using linearized superfields, $R^4$ terms in the Type II superstring effective action compactified on $T^2$ are constructed as integrals in N=2 D=8 superspace. The structure of these superspace integrals allows a simple proof of the $R^4$ non-renormalization theorems which were first conjectured by Green and Gutperle.

  1. Uniqueness of D=8 minimal supergravity with two vector multiplets

    hep-th 2026-05 unverdicted novelty 6.0 of 10

    Under a duality symmetry assumption, minimal supergravity coupled to two vector multiplets in D=8 is uniquely fixed in the BPS sector by anomaly cancellation, uplifts, and gauge enhancement.

  2. Bounds on the next-to-leading Wilson coefficient in maximal supergravity

    hep-th 2025-04 conditional novelty 6.0 of 10

    The next-to-leading Wilson coefficient in D=7 maximal supergravity is minimized at the same U-duality symmetric point as the leading coefficient, supporting string universality.
