CERN Experiment Reveals Unusual Gluon Behavior Deep Inside Atomic Nuclei

Physicists at CERN's ALICE experiment have observed a surprising drop in J/ψ particle production at the smallest scales within atomic nuclei, challenging conventional explanations for gluon behavior. This multidimensional measurement, published in Physical Review Letters, offers new insights into how gluons, which contribute significantly to the mass of ordinary matter, are distributed and interact.
