A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Owing to a phenomenon known as color confinement, quarks are never found in isolation; they can be found only within hadrons, which include baryons (such as proton… WebThe double-charm tetraquark (T + cc, cc u d) is a type of long-lived tetraquark that was discovered in 2024 in the LHCb experiment conducted at the Large Hadron Collider.
