Description
We propose a new model of D3-brane inflation in a recently constructed class of warped throat backgrounds of Type IIB Supergravity, which are modifications of the Klebanov-Strassler background in the IR region. The dilaton has a non-trivial profile along the radial direction and induces a potential for the D3-brane. This contribution to the D3-brane potential generically features an inflection point near the tip of the throat and thus may provide a new possibility to address the eta-problem.
