|| Title: Fat Inflatons, Large Turns and the η-problem

||

Abstract: I will discuss fat inflation in multifield models of inflation where all scalar fields are heavier than the Hubble scale, thus evading the so called η-problem. I will show how this is achieved in multifield inflation thanks to large turns in the field space. I will then illustrate this scenario in a D5-brane model in Type IIB string flux compactifications, where the brane moves along the angular and radial directions in a warped throat driving fat D-brane natural-like inflation, with interesting cosmological predictions.
