Abstract [en]

We investigate whether cosmological inflation is possible in a class of flux compactifications of type IIA strings on rigid Calabi-Yau manifolds, when all perturbative string corrections are taken into account. We confine ourselves to the universal hypermultiplet and an Abelian vector multiplet, representing matter in four dimensions. Since all axions can be stabilized by D-instantons, we choose the dilaton and a Kahler modulus as the only running scalars. Though positivity of their scalar potential can be achieved, we find that there is no slow roll (epsilon > 13/6), and no graceful exit because the scalar potential has the runaway behavior resulting in decompactification. We conclude that it is impossible to generate phenomenologically viable inflation in the given class of flux compactifications of type IIA strings without explicit breaking of the N = 2 local supersymmetry of the low-energy effective action.
