Hadrons

The family of particles that participate in the strong interaction. Baryons (protons, neutrons, and hyperons) and mesons (particles with masses between those of electrons and protons) are the two subfamilies. Hadrons are composed of quarks. These can be either mesons which are quark doublets or baryons which are quark triplets.
