标题： Accidental Kähler Moduli Inflation

摘要： 我们研究了IIB型弦理论中一种意外膨胀模型，在该模型中，膨胀发生在小Kähler模的拐点附近。 跑道结构有助于缓解已知的担忧，即弦环修正可能会破坏Kähler模膨胀，除非通过弦耦合或特殊的膜设置获得显著抑制。 此外，模稳定和膨胀动力学分离所需的规范群等级层次被放宽。 当我们使用最近提出的由D项生成的跑道模型时，这种放松变得更加显著。 显示英文摘要

摘要： We study a model of accidental inflation in type IIB string theory where inflation occurs near the inflection point of a small K\"ahler modulus. A racetrack structure helps to alleviate the known concern that string-loop corrections may spoil K\"ahler Moduli Inflation unless having a significant suppression via the string coupling or a special brane setup. Also, the hierarchy of gauge group ranks required for the separation between moduli stabilization and inflationary dynamics is relaxed. The relaxation becomes more significant when we use the recently proposed D-term generated racetrack model.
