# Global Orientifolded Quivers with Inflation

## TL;DR

This paper constructs a comprehensive type IIB string theory model embedding chiral visible sectors and inflation within a Calabi-Yau compactification, achieving moduli stabilization and de Sitter vacuum with explicit examples.

## Contribution

It provides the first explicit Calabi-Yau example combining an inflationary sector with a chiral visible sector in a global orientifolded quiver setup.

## Key findings

- Successful realization of inflation driven by a del Pezzo divisor.
- Full moduli stabilization in a de Sitter vacuum.
- Explicit Calabi-Yau example with both inflation and chiral sectors.

## Abstract

We describe global embeddings of fractional D3 branes at orientifolded singularities in type IIB flux compactifications. We present an explicit Calabi-Yau example where the chiral visible sector lives on a local orientifolded quiver while non-perturbative effects, $\alpha'$ corrections and a T-brane hidden sector lead to full closed string moduli stabilisation in a de Sitter vacuum. The same model can also successfully give rise to inflation driven by a del Pezzo divisor. Our model represents the first explicit Calabi-Yau example featuring both an inflationary and a chiral visible sector.
