Sakita-miwa Classification Access

How to systematically classify the rapidly growing “particle zoo” of hadrons (mesons and baryons) based on symmetry principles, without assuming quarks as physical entities.

The Sakita–Miwa classification was a correct and valuable symmetry-based description of hadrons, equivalent to the Eightfold Way in predictive power. Its main weakness was not embracing quarks as real objects — a defensible caution in the 1960s, but a fatal limitation after 1968. Today, it is a historical milestone rather than a working tool. Recommended reading for students of particle physics history, but not for modern phenomenology. sakita-miwa classification
