Supersymmetric Standard Models, Flux Compactification and Moduli Stabilization

TL;DR

This paper constructs and classifies supersymmetric string theory models with fluxes that stabilize key moduli, leading to realistic Standard Model-like vacua with potential for further moduli stabilization.

Contribution

It introduces new flux compactification models on orientifolds that stabilize complex structure moduli and the dilaton, expanding the landscape of realistic string vacua.

Findings

Identified models with 2 and 4 families stabilized by fluxes.

Found models with additional gauge factors and negative beta functions.

Suggested gaugino condensation could stabilize Kahler moduli.

Abstract

Based on the T-dual constructions of supersymmetric intersecting D6-models on Z_2 x Z_2 orientifolds, whose electroweak sector is parallel with the orientifold planes with Sp(2f)_L x Sp(2f)_R gauge symmetry (hep-th/0407178), we derive and classify Standard Model-like vacua with RR and NSNS fluxes, which stabilize toroidal complex structure moduli and the dilaton. We find consistent four-family (f=4) and two-family (f=2) models with one- and two-units of the quantized flux, respectively. Such models typically possess additional gauge group factors with negative beta functions and may lead, via gaugino condensation, to stabilization of toroidal Kahler moduli. These models have chiral exotics.
