QuickTime™ and a decompressor

Slow-roll inflation is forbidden in the most clearly understood class of compactifications: in the large volume and small string
coupling limit of all Calabi-Yau orientifold compactifications when
only standard NS-NS three-form flux, R-R fluxes, D6-branes and O6-planes are included. With these ingredients, the first slow-roll
parameter satisfies ϵ ≥ 27/13 whenever V > 0..
