CERN Experiment Challenges Gluon Behavior Theories in Atomic Nuclei

The ALICE experiment at CERN's Large Hadron Collider has produced the first multidimensional measurement of incoherent J/ψ photonuclear production. This research, published in Physical Review Letters, offers a clearer understanding of gluon arrangement within atomic nuclei at high energies. The findings could help distinguish between competing theoretical explanations of how gluons contribute to the mass of the visible universe, impacting fundamental physics and our understanding of matter.
