| The simplest hadrons are therefore mesons made from a quark and antiquark pair, and baryons made of three quarks. |
| However, we find it difficult to describe the way that quarks and gluons bind together to form hadrons. |
| Gluons are bosons, carriers of the strong force that bind quarks together into hadrons such as protons or neutrons. |
| Beams of hadrons, such as protons, neutrons and ions, offer important advantages over X-ray radiotherapy. |
| At low temperatures, quarks are confined in hadrons, whereas at higher temperatures they form a quark-gluon plasma. |
| This process results in two jets of hadronic particles as the quarks form hadrons. |
