Related to Baryons: Mesons, Quarks, Hadrons


Any of a class of subatomic particles that are both hadrons and fermions, are composed of three quarks, participate in strong interactions, and are generally more massive than mesons and leptons. The class of baryons is divided into the nucleons and hyperons.

[Greek barus, heavy; see gwerə- in Indo-European roots + -on.]

bar′y·on′ic adj.


(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 . Baryons are either nucleons or hyperons. The baryon number is the number of baryons in a system minus the number of antibaryons
[C20: bary-, from Greek barus heavy + -on]


(ˈbær iˌɒn)

any strongly interacting fermion, as a proton or neutron, that decays into a set of particles that includes a proton.
