Super Covering Maps

High Energy Physics - Theory 2026-02-06 v2

Abstract

We define analytic maps between super Riemann surfaces which extend the notion of branched covering maps to a supersymmetric setting. We show that these super covering maps appear naturally both in symmetric product orbifolds of superconformal field theories, as well as in the hybrid formalism for tensionless string theory on AdS3×S3×T4\text{AdS}_3\times S^3\times\mathbb{T}^4. In the former, they can be used to calculate correlators in a manifestly supersymmetric way, while in the latter they solve Ward identities of correlators with spacetime supersymmetry.
