Physicists discover a heavy cousin of the proton at CERN’s Large Hadron Collider

A new subatomic particle known as the Ξcc⁺ has been discovered at CERN’s Large Hadron Collider. This heavy proton-like particle contains two charm quarks and was detected using the upgraded LHCb experiment. Scientists observed it through its decay into lighter particles in high-energy collisions. The finding confirms predictions and settles a decades-long question about its existence.

Scientists discover exotic proton-like particle

Scientists announced the discovery of a new heavy, proton-like particle in experiments with the Large Hadron Collider (LHC), the world's most powerful particle accelerator, at the European Organization for Nuclear Research (CERN) on Tuesday.

Scientists at CERN discover new heavy-proton subatomic particle

Over a century ago, Ernest Rutherford discovered the proton by splitting the atom in a laboratory in Manchester. Today, researchers based in Manchester have discovered a new particle that Rutherford would never have imagined: a “heavier” version of the proton that had been theorized but never clearly observed until now, thanks to recent data from CERN’s particle accelerator, which is the world’s most powerful particle accelerator. The University…
