The international LHCb collaboration at the Large Hadron Collider (LHC) has discovered three new particles. These are namely- a new type of pentaquark and the first-ever pair of tetraquarks, which contains a new variety. The outcomes, proposed today at a CERN seminar, added three exotic members to the expanding list of hadrons at the LHC. This will enable the physicists to better understand how quarks attach themselves to these composite particles.

Quarks are elemental particles and appear in six flavors: up, down, charm, strange, top, and bottom. They generally incorporate together in groups of twos and threes to form hadrons like protons and neutrons that compose the atomic nuclei. However, they can also assemble into four-quark and five-quark particles, or “tetraquarks” and “pentaquarks.”

These exotic hadrons were foreseen by theorists and the conventional hadrons approximately six decades ago, but recently, in the last 20 years, they have been observed by LHCb and other experiments.

The discoveries declared today by the LHCb collaboration incorporate new kinds of exotic hadrons. “Finding new kinds of tetraquarks and pentaquarks and measuring their properties will help theorists develop a unified model of exotic hadrons, the exact nature of which is largely unknown,” says LHCb spokesperson Chris Parkes. “It will also help to better understand conventional hadrons.”
