(FILES) A handout made available by the European Organization for Nuclear Research (CERN) on April 19, 2023, shows the tunnels of the Future Circular Collider (FCC) and the current Large Hadron Collider (LHC) in Geneva. The Large Hadron Collider has discovered a new particle, the 80th identified so far by the world's most powerful particle smasher, Europe's CERN physics laboratory announced on MArch 17, 2026. The new particle has been named "Xi-cc-plus". Scientists hope the particle, which is similar to a proton but four times heavier, will reveal more about the strange behaviour of quantum mechanics.
