On the effective theory of type IIA AdS_4 compactifications

TL;DR

This paper analyzes the low energy effective theory of type IIA AdS_4 flux compactifications on nilmanifolds and cosets, computing the superpotential, Kähler potential, and moduli mass spectrum, with cross-checks via Kaluza-Klein reduction.

Contribution

It provides explicit calculations of the superpotential, Kähler potential, and moduli masses for specific compactifications, including validation through Kaluza-Klein analysis.

Findings

Explicit superpotential and Kähler potential derived.

Mass spectrum of light moduli computed and validated.

Cross-check confirms consistency of the effective theory.

Abstract

This is a summary of arXiv:0806.3458, where the low energy effective theory of type IIA AdS_4 N=1 flux compactifications on nilmanifolds and cosets has been analyzed. We compute the superpotential, the K\"ahler potential and the mass spectrum for the light moduli. For the nilmanifold examples we perform a cross-check on the result for the mass spectrum by calculating it from a direct Kaluza-Klein reduction.
