Heterotic String Theory on non-Kaehler Manifolds with H-Flux and Gaugino Condensate

TL;DR

This paper explores heterotic string compactifications on non-Kaehler manifolds with H-flux and gaugino condensates, aiming to achieve stable vacua with zero cosmological constant and analyzing the effective superpotential.

Contribution

It introduces a framework for balancing H-flux and gaugino condensates in heterotic compactifications on non-Kaehler manifolds to obtain stable, zero cosmological constant vacua.

Findings

Balanced H-flux and gaugino condensate can produce stable vacua

Effective superpotential describes these heterotic vacua

Conditions for zero cosmological constant identified

Abstract

We discuss compactifications of heterotic string theory to four dimensions in the presence of H-fluxes, which deform the geometry of the internal manifold, and a gaugino condensate which breaks supersymmetry. We focus on the compensation of the two effects in order to obtain vacua with zero cosmological constant and we comment on the effective superpotential describing these vacua.
