Supersymmetric Moduli Stabilization and High-Scale Inflation

Understand

We study the back-reaction of moduli fields on the inflaton potential in generic models of F-term inflation.

• We derive the moduli corrections as a power series in the ratio of Hubble scale and modulus mass.
• The general result is illustrated with two examples, hybrid inflation and chaotic inflation.
• We find that in both cases the decoupling of moduli dynamics and inflation requires moduli masses close to the scale of grand unification.
