$Z_N$ Orientifolds with Flux

TL;DR

This paper analyzes type IIB $Z_N$ orientifolds with flux, computing flux-induced tadpoles and superpotentials to explore moduli stabilization, supersymmetric vacua, and brane configurations, including partial moduli fixing with anti D3-branes.

Contribution

It provides explicit calculations of flux effects and identifies conditions for moduli stabilization and supersymmetric vacua in $Z_N$ orientifolds, including brane configurations.

Findings

Found supersymmetric vacua with $g_s<1$

Identified brane configurations with canceled tadpoles

Showed partial moduli fixing unless anti D3-branes are included

Abstract

We compute the flux induced tadpole and superpotential in various type IIB $Z_N$ compact orientifolds in order to study moduli stabilization. We find supersymmetric vacua with $g_s < 1$ and describe brane configurations with cancelled tadpoles. In some cases moduli are only partially fixed unless anti D3-branes are included.
