MTheory on Seven Manifolds with Gfluxes
Abstract
We compactify Mtheory on sevenmanifolds with a warpfactor and Gfluxes on the internal space. Because of nonzero Gfluxes, we are forced to adopt a Majorana supersymmetry spinor ansatz which does not have the usual direct product structure of two lower dimensional Majorana spinors. For the spinor ansatz that we choose, we find that supersymmetry puts strong constraints on the internal space namely that it must be conformal to a Ricciflat sevenmanifold of the form $X^7= X^6 \times X^1$. The holonomy of $X^6$ must be larger than 1 if the warpfactor is to be nontrivial. The warpfactor depends only on the $X^1$ direction and is singular. We argue that to avoid this singularity one has to embed this solution in a HoravaWitten setup and thus has natural links to much studied braneworld scenarios.
