| 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. |
| This was a deadly flaw for a theory of hadrons, but not for a theory in which all matter, including photons, are strings. |
| Beams of hadrons, such as protons, neutrons and ions, offer important advantages over X-ray radiotherapy. |
| According to quantum field theory, gluons and pairs of light quarks and antiquarks should be spontaneously emitted and re-absorbed by the quarks and gluons inside hadrons. |
| Charmed hadrons are produced by the interaction of high energy photons with a segmented beryllium oxide target. |
