Contribution
It introduces a superpotential for G_2 compactifications with fluxes and explores the resulting stable non-supersymmetric vacuum structure in M-theory.
Findings
Fluxes drive the Freund-Rubin parameter to zero.
A stable non-supersymmetric vacuum with negative cosmological constant is found.
A simple model incorporates supersymmetry breaking effects.
Abstract
We discuss the effective action for weak G_2 compactifications of M-theory. The presence of fluxes acts as a source for the the axions and drives the Freund-Rubin parameter to zero. The result is a stable non-supersymmetric vacuum with a negative cosmological constant. We also give the superpotential which generates the effective potential and discuss a simple model which aims to incorporate the effects of supersymmetry breaking by the gauge sector.
