在一个精致的赛道通货膨胀

Inflation in a refined racetrack

Wen-Yu Wen

摘要:

在本文中,我们通过引入开弦模量来改进arXiv:hep-th/0406230中构建的跑道膨胀模型。这个模编码了我们的膜世界在卡-丘喉中的嵌入。我们认为,在一般情况下,这种开弦模动态地运行与暴胀场由于其非线性耦合。全面的分析变得困难,因为标量势在暴胀时期逐渐变化。然而,通过显式构造,我们仍然能够通过适当选择初始条件来建立一个现实的模型。

英文摘要:

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.
