Abstract

We give an explicit quotient description of the (n_R−3|n_R/2−2)-dimensional supermoduli space M_{0,n_R} of genus zero super Riemann surfaces with n_R≥4 Ramond punctures and prove that it is a Deligne-Mumford superstack. We also give an explicit quotient description of the supermoduli stack of genus zero supercurves with no SUSY structure.
