In this note, we refine the racetrack inflation model constructed in arXiv:hep-th/0406230 by including the open string modulus. This modulus encodes the embedding of our braneworld inside some Calabi-Yau throat. We argue that in generic this open string modulus dynamically runs with the inflaton field thanks to its nonlinear coupling. A full analysis becomes difficult because the scalar potential changes progressively during the inflation epoch. Nevertheless, by explicit construction we are still able to build a realistic model through appropriate choices of the initial conditions.

The paper
Original abstract
In this note, we refine the racetrack inflation model constructed in arXiv:hep-th/0406230 by including the open string modulus. This modulus encodes the embedding of our braneworld inside some Calabi-Yau throat. We argue that in generic this open string modulus dynamically runs with the inflaton field thanks to its nonlinear coupling. A full analysis becomes difficult because the scalar potential changes progressively during the inflation epoch. Nevertheless, by explicit construction we are still able to build a realistic model through appropriate choices of the initial conditions.

In this section we would like to argue that the open string modulus, denoted as $ϕ$, which was priorly dropped off in [ref] , may not be consistently integrated out at its supersymmetric vev thanks to the coupling with inflaton $T$ through the exponential terms.

In particular, as a simple example to the latter category, an inflation model was developed using a racetrack potential inspired by KKLT construction [ref] within the context of type IIB string theory [ref] , and later refined by an explicit construction [ref] of specific orbifolded Calabi-Yau manifold with two Kähler moduli [ref] .
