CERN Experiment Finds Evidence of Gluon Saturation in Atomic Nuclei

Physicists at CERN's ALICE experiment have made the most detailed measurements of gluon behavior within atomic nuclei, finding evidence for gluon saturation. This phenomenon, where gluons become densely packed and limit their numbers, was predicted by quantum chromodynamics. Published in Physical Review Letters, these results offer new insights into the fundamental structure of matter and challenge previous explanations.
