LHC Alchemy: Lead Transmuted into Gold!
2025-05-09
The ALICE collaboration at CERN's Large Hadron Collider (LHC) has reported the observation of lead nuclei transforming into minuscule amounts of gold during near-miss collisions. Intense electromagnetic fields generated by these high-energy collisions knock out protons from lead nuclei, resulting in the creation of gold. While the amount of gold produced is incredibly small (29 picograms), this achievement fulfills a long-held alchemic dream. The study provides insights into electromagnetic dissociation and improves theoretical models used to understand beam losses in the LHC, ultimately enhancing its performance.
