## Contribution

It provides the first explicit string theory embedding of axionic Euclidean wormholes in AdS backgrounds, strengthening their theoretical foundation.

## Key findings

- Explicit regular axionic wormhole solutions in Type IIB string theory
- Precise derivation of axion content via AdS/CFT correspondence
- Discussion of the paradoxical implications of these wormholes

## Abstract

We find regular axionic Euclidean wormhole solutions in Type IIB string theory compactified on $\text{AdS}_5\times \text{S}^5/\mathbb{Z}_k$. AdS/CFT enables a precise derivation of the axion content of the Euclidean theory, placing the string theory embedding of the wormholes on firm footing. This further sharpens the paradox posed by these solutions.
