Abstract

By 1960 a great number of particles (which decay weakly) and resonances (which decay strongly) had been discovered. Some are seen in production reactions, where they are produced along with other final-state particles (such as the ω meson in p\(\bar p\) → π+π ω), others in formation reactions, where they are the only products of collisions between the incident particles (such as the isobar resonance Δ in πp →Δ). This proliferation of particles and resonances calls for an organizing scheme more powerful than the Gell-Mann-Nishijima relation — in fact, a model that could embody the main features of known symmetry principles, establish or suggest relationships among particles, and provide a good basis for an eventual dynamic approach.
