baryon octet

[′bar·ē‚än äk′tet]

(particle physics)

The group of one lambda, three sigma, and two xi hyperons and two nucleons, all having spin ½ and positive parity, and forming a symmetrical pattern as suggested by SU₃ symmetry.

We consider only normal and strange matter, that is, the baryons and mesons constituted by u, d and s quarks: the baryon octet (spin 1/2 baryons), the baryon decouplet (spin 3/2 baryons), the pseudoscalar meson nonet (spin 0 mesons), and the vector meson nonet (spin 1 mesons), which leaves us with a total of 54 particles (18 baryons, 18 antibaryons, and 18 mesons).
