Physicists at CERN's LHCb experiment discovered the Xicc+ particle, an exotic baryon made of two charm quarks and a down quark, resolving a 20-year-old mystery about its mass and properties. The discovery, confirmed with over 7-sigma statistical significance, could illuminate how the strong nuclear force binds heavier quarks together and advance understanding of particle physics.
