CERN's ALICE Collaboration Discovers Quark Systems in Collisions

4/9/2026

Summary

Story summary

The ALICE Collaboration at CERN observed anisotropic flow patterns in baryons and mesons during proton-proton and proton-lead collisions at the Large Hadron Collider, suggesting small collision systems can produce quark systems.
The results support existing models of quark-gluon plasma formation.
However, some discrepancies remain, prompting further research with oxygen collisions recorded in 2025.
The ongoing work aims to enhance understanding of the universe's conditions shortly after the Big Bang.
