Abstract
The Pierre Auger Observatory has revealed a significant challenge in air shower physics: a discrepancy between the simulated and observed muon content in cosmic-ray interactions, known as the 'Muon Puzzle'. This issue stems from a lack of understanding of high-energy hadronic interactions. Current state-of-the-art hadronic interaction models fall short, underscoring the need for improvements. In this contribution, we explore the integration of the Pythia 8 hadronic interaction model into air shower simulations. While Pythia 8 is primarily used in Large Hadron Collider experiments, recent advancements in its Angantyr module show promise in better describing hadron-nucleus interactions, making it a valuable tool for addressing the Muon Puzzle.

Reports on this Submission
Strengths
1- This is a nice little note on the possibility to use Pythia in the simulation in air showers.
2- Bringing LHC and cosmic ray studies into closer contact is good.
3- The plan to increase the use of Rivet is also welcome.
Weaknesses
1- The text narrows down on solving the muon puzzle, at the expense of the bigger picture.
Report
It deserves publication, after the requested minor changes.
Requested changes
1- It should be mentioned that (so far) Angantyr has only been developed for high-energy collisions, i.e. RHIC and LHC, and that this will make it difficult to draw strong conclusions from comparisons with NA61/SHINE data.
2- l.5 "divided" -> "divided into"
3- l.26 "study can be applied to" -> "studies can be applied"
4- l.41 "case" -> "case of"
5- l.50 "in" -> "into"
6- l.87 "which is" -> "which are" (?, unclear if it refers to "approach" or "algorithms", so maybe rewrite whole sentence)
