MSSM vacua from Flux Compactifications

TL;DR

This paper constructs novel four-dimensional Minkowski string vacua with fluxes that are chiral, free of tadpoles, and preserve N=1 or N=0 supersymmetry, featuring MSSM-like spectra and stabilized moduli.

Contribution

It presents the first explicit construction of flux compactification vacua with these specific properties, including chirality, tadpole cancellation, and MSSM-like features.

Findings

MSSM-like low energy spectrum achieved

Moduli stabilized in the flux background

Supersymmetry softly broken by fluxes

Abstract

We construct the first D = 4 Minkowski string theory vacua of flux compactification which are (i) chiral, (ii) free of NSNS and RR tadpoles, and (iii) N = 1 or N = 0 supersymmetric. In the latter case SUSY is softly broken by the fluxes, with soft terms being generated in the gauge and chiral sectors of the theory. In addition, the low energy spectrum of the theory is MSSM-like, the dilaton/complex structure moduli are stabilized and the supergravity background involves a warped metric.
