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.

Physicists Discover a Third Type of Quantum Particle That Breaks the Rules of Three-Dimensional Physics

For a century, every particle ever found has belonged to one of exactly two groups, and physicists assumed that was all there would ever be. A pair of studies published in Physical Review A in February 2026 now describes a third type, one that sits outside both groups entirely, behaves in ways that have no […] The post Physicists Discover a Third Type of Quantum Particle That Breaks the Rules of Three-Dimensional Physics appeared first on Above …
