Scientists discover heavier version of proton with upgraded detector

AI Summary

medium article 3 min

Scientists at CERN's Large Hadron Collider (LHC) have discovered a heavier version of the proton, named Xi-cc-plus, using an upgraded LHCb detector. The particle, four times heavier than a regular proton, was identified through its decay signature after being created in high-energy proton collisions. The discovery allows physicists to further refine their understanding of the strong nuclear force, which binds atomic nuclei. The upgraded detector allowed for the particle's detection after only one year, whereas it was undetectable with the original LHCb. The newfound particle contains two charm quarks instead of the two up quarks found in a regular proton.
