Abstract
We study the supergravity hybrid inflation model ofAntusch in the presence of a modulus field. Theη-problem is solved by a shift symmetry for the inflaton, whichprotects the inflaton mass even in the presence of the modulus field.Inflation is (nearly) unaffected by moduli stabilization, provided thescale of supersymmetry breaking in the post-inflation vacuum is small.Therefore the model has the nice phenomenology that it combines lowscale supersymmetry breaking with high scale (grand unification scale)inflation.
