| As this discussion makes clear, the issue of exotic hadrons exposes profound weaknesses in our current understanding of the strong interaction. |
| The simplest hadrons are therefore mesons made from a quark and antiquark pair, and baryons made of three quarks. |
| At low temperatures, quarks are confined in hadrons, whereas at higher temperatures they form a quark-gluon plasma. |
| Beams of hadrons, such as protons, neutrons and ions, offer important advantages over X-ray radiotherapy. |
| This was a deadly flaw for a theory of hadrons, but not for a theory in which all matter, including photons, are strings. |
| This process results in two jets of hadronic particles as the quarks form hadrons. |
