⚛️ A New Particle Has Been Found at the Large Hadron Collider

CERN’s LHCb collaboration has announced the discovery of Ωcc⁺ — a baryon made of two charm quarks and one strange quark.

It was the final missing particle in the family of doubly charmed baryons. LHCb discovered Ξcc⁺⁺ in 2017 and Ξcc⁺ in 2026. With Ωcc⁺, physicists have now completed the basic trio predicted by strong-interaction theory more than 50 years ago.

Ωcc⁺ lives for an incredibly short time: it is produced in proton–proton collisions, travels only a tiny fraction of a millimetre, and then decays. Scientists reconstructed it from the tracks left behind in the LHCb detector.

This is an important test of quantum chromodynamics — the theory that explains how quarks are bound inside protons, neutrons and other particles.
