A remarkable feature of the recently published Planck data is that one of the oldest models of inflation, the R^2 inflation model proposed by Starobinsky, fits the data strikingly well. In this talk, I show how the Starobinsky model arises asymptotically in the large field limit of a supergravity D-term hybrid inflation model based on an approximate superconformal symmetry. This ...

We study the effects of coupling hybrid inflation to moduli stabilization as employed in certain type IIB string compactifications with D-branes and fluxes. In a scenario with a single Kahler modulus stabilized in a racetrack potential, F-term hybrid inflation is unfeasible due to either a large inflaton mass or a tachyonic direction. However, we present a working model of D-term hybrid...
