New CERN Measurement Challenges Theories of Gluon Behavior in Atomic Nuclei

The ALICE experiment at CERN's Large Hadron Collider has released a new measurement, published in Physical Review Letters, that provides the first multidimensional data on incoherent J/ψ photonuclear production. This research offers an unprecedented view of how gluons are arranged within atomic nuclei at high energies, challenging existing theories about their behavior and advancing the understanding of how matter acquires its mass and structure.
