This week, the LHCb experiment at CERN's Large Hadron Collider announced the discovery of five new resonances (very short-lived particles), known as excited Ωc (Omega_c) baryons. Baryons are composed of three fundamental particles called quarks. Well-known examples of baryons are the protons and neutrons that are found in atomic nuclei. A proton is made of two “up” quarks and one “down” quark, bound together via the strong nuclear force.
