New argument in favor of asymptotic SU(3):32+-decuplet mass spacing and decays

We argue that the recent indication from high-statistics experiments that the ${\frac{3}{2}}^{+}$ decuplet satisfies equal mass-squared spacing favors a nonperturbative point of view towards broken SU(3), i.e., an algebraic approach based on the hypothesis of asymptotic SU(3) in which, apart from a mixing effect, the Gell-Mann-Okubo mass formula is exact. A further test in the strong decays of hadrons involving pseudoscalar-meson emission is also discussed. We also add a critical remark about the SU(3) formula traditionally used in the SU(3) test of strong decays of hadrons involving pseudoscalar-meson emission.
