Abstract

We find a general model of \em single-field inflation within the context of type IIB string theory compactified on large volume Calabi-Yau orientifolds with h^2,1 > h^1,1 = 2. The inflaton is the axion part of the complexified Kähler moduli and the resulting scalar power spectrum is red, and can easily be made compatible with WMAP3 bounds on n_s. This model overcomes the η-problem using gaugino condensates on wrapped D7-brane while keeping the tuning of the parameters minimal.
