Abstract
Over the last decade, the outstanding fact about hadronic states and hadronic interactions has been their property of SU (3) symmetry. More correctly, the symmetry established has been that of the factor group SU(3)/Z3, the octet symmetry. This symmetry does not hold exactly; in fact, the deviations from SU (3) symmetry are typically ≈ ± 200 MeV for the hadronic mass values within a particular SU (3) multiplet. This may be contrasted with the situation for its isospin subgroup SU(2) τ , for which the symmetry is believed to hold to a rather high degree of accuracy. The deviations from isospin symmetry are typically ≈ ± 2 MeV for the hadronic masses within a particular isospin multiplet, and even these deviations are all attributable to the effects of the electromagnetic interactions, which violate this SU(2) τ symmetry in a known way.
