baryon (plural baryons)

1. (physics) A heavy subatomic particle created by the binding of quarks by gluons; a hadron containing three quarks. Baryons have half-odd integral spin and are thus fermions. This category includes the common proton and neutron of the atomic nucleus.
   • 1953 October 1, A. Pais, “On the Baryon-meson-photon System”, in Progress of Theoretical Physics, volume 10, number 4, page 457:

     Without prejudging on the actual nature of the relationship between the V₁ and the nucleon it seems practical to have a collective name for these particles and other which possibly may still be discovered and which may also have to be taken along in the conservation principle just mentioned. It is proposed to use the fitting name "baryon" for this purpose.
