Why turkey has the same name as Turkey
quasi-stable member of a class of subatomic particles known as baryons that are composed of three quarks. More massive than their more-familiar baryon cousins, the nucleons (protons and neutrons), hyperons are distinct from them in that they contain one or more strange quarks. Hyperons, in order of increasing mass, include the lambda-zero (Lambda0) particle, a triplet of sigma (Sigma) particles, a doublet of xi (Xi) particles, and the omega-minus (Omega) particle. Each of the seven particles, detected during the period 1947-64, also has a corresponding antiparticle. The discovery of the omega-minus hyperon was suggested by the Eightfold Way of classifying hadrons, the more-general group of subatomic particles to which hyperons are assigned. Hadrons are composed of quarks and interact with one another via the strong force.
