| Beams of hadrons, such as protons, neutrons and ions, offer important advantages over X-ray radiotherapy. |
| This process results in two jets of hadronic particles as the quarks form hadrons. |
| At low temperatures, quarks are confined in hadrons, whereas at higher temperatures they form a quark-gluon plasma. |
| Gluons are bosons, carriers of the strong force that bind quarks together into hadrons such as protons or neutrons. |
| In collisions at high energies, charmonium particles come from the decay of b-flavoured hadrons and prompt production. |
| As this discussion makes clear, the issue of exotic hadrons exposes profound weaknesses in our current understanding of the strong interaction. |
