2 00 5 Flux and Freund - Rubin Superpotentials in M - theory
We discuss the effective action for weak G2 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...

متن کاملFreund-rubin Revisited
We utilise the duality between M theory and Type IIA string theory to show the existence of Freund-Rubin compactifications of M theory on 7-manifolds with singularities supporting chiral fermions. This leads to a concrete way to study phenomenologically interesting quantum gravity vacua using a holographically dual three dimensional field theory. bacharya, denef, hofman, [email protected]...
متن کاملSuperpotentials from flux compactifications of M-theory
In flux compactifications of M-theory a superpotential is generated whose explicit form depends on the structure group of the 7-dimensional internal manifold. In this note, we discuss superpotentials for the structure groups: G2, SU(3) or SU(2). For the G2 case all internal fluxes have to vanish. For SU(3) structures, the non-zero flux components entering the superpotential describe an effectiv...
