We establish the equivalence between two formulations of superstring perturbation theory, one based on integration over the supermoduli space of super Riemann surfaces (SRS), the other based on integration over the bosonic moduli space with insertions of picture changing operators (PCO) on the worldsheet and the vertical integration prescription, by showing how the latter arises from a specific construction of the supermoduli integration contour.

Yang-Mills Theory From Super Moduli Space
hep-th 2025-01 conditional novelty 6.0 of 10

A spinning superparticle world-line path integral pulled back to super moduli space yields a space-time action that is Yang-Mills theory up to boundary terms and non-local corrections.
