# $\large{\alpha'}$-Corrections and de Sitter Vacua - a Mirage?

## TL;DR

This paper investigates the impact of $$-corrections on type IIB string compactifications, proposing a model-independent approach to realize de Sitter vacua and slow-roll inflation through flux tuning.

## Contribution

It introduces a novel, model-independent framework for achieving de Sitter vacua and inflation in type IIB compactifications considering $$-corrections.

## Key findings

- Proposes a scenario for non-supersymmetric Minkowski and de Sitter vacua.
- Demonstrates tuning of flux superpotential can stabilize K"ahler moduli.
- Suggests mechanisms for slow-roll inflation in one-modulus models.

## Abstract

In this work we analyze the role of $\alpha '$-corrections to type IIB orientifold compactifications in K\"ahler moduli stabilization and inflation. In particular, we propose a model independent scenario to achieve non-supersymmetric Minkowski and de Sitter vacua for geometric backgrounds with positive Euler-characteristic and generic number of K\"ahler moduli. The vacua are obtained by a tuning of the flux superpotential. Moreover, in the one-modulus case we argue for a mechanisms to achieve model independent slow-roll.
