baryon

bar·y·on  (br-n)

n.

Any of a family of subatomic particles, including the nucleon and hyperon multiplets, that participate in strong interactions, are composed of three quarks, and are generally more massive than mesons. Also called heavy particle. See Table at subatomic particle.

baryon [ˈbærɪˌɒn]

n

(Physics / Atomic Physics) any of a class of elementary particles that have a mass greater than or equal to that of the proton, participate in strong interactions, and have a spin of ½. Baryons are either nucleons or hyperons. The baryon number is the number of baryons in a system minus the number of antibaryons

[bary-, from Greek barus heavy + -on]

baryon  (br-n)

Any of a family of subatomic particles composed of three quarks or three antiquarks. They are generally more massive than mesons, and interact with each other via the strong force. Baryons form a subclass of hadrons and are subdivided into nucleons and hyperons. Protons and neutrons are baryons. See Table at subatomic particle.
