Accidental K\"ahler Moduli Inflation

Understand

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.
