CERN Spots New Double-Charmed Baryon Xi-cc-plus After Upgrades
TL;DR Summary
CERN’s LHCb collaboration announced the discovery of a new baryon called Xi-cc-plus, containing two charm quarks and one down quark, making it the 80th identified particle and the first new one found after the LHCb upgrades completed in 2023. It is heavier than a proton and has a shorter lifetime—about six times shorter than a similar earlier particle—posing detection challenges but providing a test bed for quantum chromodynamics and guiding future collider plans like the Future Circular Collider.
