hadron definitions

WordNet (r) 3.0 (2005)

n
1: any elementary particle that interacts strongly with other particles

Merriam Webster's

noun Etymology: International Scientific Vocabulary hadr- thick, heavy (from Greek hadros thick) + 2-on Date: 1962 any of the subatomic particles (as protons and neutrons) that are made up of quarks and are subject to the strong force hadronic adjective

Britannica Concise

Any of the subatomic particles that are built from quarks and thus interact via the strong force. The hadrons fall into two groups: mesons and baryons. Except for protons and neutrons, which are bound in nuclei, all hadrons have short lives and are produced in high-energy collision of subatomic particles. All hadrons are subject to gravitation; charged hadrons are subject to electromagnetic forces. Some hadrons break up by way of the weak force (as in radioactive decay); others decay via the strong and electromagnetic forces.

Oxford Reference Dictionary

n. Physics any strongly interacting elementary particle. Derivatives: hadronic adj. Etymology: Gk hadros bulky
