ATLAS Uses Proton-Oxygen Collisions to Recreate Cosmic-Ray Showers in the Lab
ATLAS has reported its first measurement of proton-oxygen collisions at the Large Hadron Collider, providing data intended to improve simulations of cosmic-ray showers in Earth’s atmosphere
Key Takeaways
- The LHC ran proton-oxygen collisions for the first time in July 2025
- ATLAS measured charged-particle production to test models used by cosmic-ray observatories
