Moduli of log twisted $\mathcal{N}=1$ SUSY curves

Abstract

The goal of the present paper is to construct a smooth compactification of the moduli superstack classifying pointed $\mathcal{N}=1$ SUSY (= ${\text{SUSY}}_1$) curves. This construction is based on the Abramovich-Jarvis-Chiodo compactification of the moduli stack classifying spin curves. First, we give a general framework of a theory of log superschemes (or more generally, log superstacks). Then, we introduce the notion of a pointed (stable) log twisted ${\text{SUSY}}_1$ curve; it may be thought of as a logarithmic and twisted generalization of the classical notion of a pointed ${\text{SUSY}}_1$ curve, as well as a supersymmetric analogue of the notion of a pointed (log) twisted curve. The main result of the present paper asserts that the moduli superstack classifying pointed stable log twisted ${\text{SUSY}}_1$ curves may be represented by a log superstack whose underlying superstack is a superproper and supersmooth Deligne-Mumford superstack. Consequently, this moduli superstack forms a smooth compactification different from the compactification proposed by P. Deligne.
