The Overshoot Problem in Inflation after Tunneling, Koushik Dutta (DESY)

Aug. 29 - 20:30 - 2011

Abstract: In the 'landscape' paradigm of String Theory, our observable Universe may originate via a tunneling event from a nearby metastable false vacuum, followed by sufficient amount of inflation. We discuss the overshoot problem in this set-up and show explicitly that there is no overshoot problem for higher order monomial potentials. The results substantially alleviate the initial value problem for "small-field" inflation models.
