Perturbative superstring theory is revisited, with the goal of giving a simpler and more direct demonstration that multi-loop amplitudes are gauge-invariant (apart from known anomalies), satisfy space-time supersymmetry when expected, and have the expected infrared behavior. The main technical tool is to make the whole analysis, including especially those arguments that involve integration by parts, on supermoduli space, rather than after descending to ordinary moduli space.

  1. A New Term in Type II Effective Action

    hep-th 2026-07 unverdicted novelty 8.0 of 10

    One-loop type II effective actions contain a dilaton times Euler-density term from superconformal ghost zero modes, resolving a black-hole index puzzle on Calabi-Yau spaces.

  2. Non-abelian asymmetric orbifolds with vanishing one-loop vacuum energy

    hep-th 2026-07 conditional novelty 6.0 of 10

    A classification finds 17 four-dimensional Type II asymmetric orbifolds with non-abelian point groups and pointwise vanishing one-loop vacuum energy, each also realizable as a Scherk-Schwarz compactification.

  3. B-RNS-GSS formalism and $L_{\infty}$-actions

    hep-th 2025-10 conditional novelty 6.0 of 10

    The B-RNS-GSS similarity transformation is the strictification flow of an L-infinity action of supersymmetry, R = P exp(∫₀¹ dt A) with A given by explicit RNS currents — exact in θ, where the prior literature had only...
