Abstract

The recently discovered f-wave dominance of the decay F₃₅ (1877) → Δπ is interpreted as requiring mixing between 56, L = 2 and 70, L = 2 baryon multiplets. This conclusion is drawn in the context of a broken version of SU(6)_W. Further predictions include (a) the existence of a second prominent F₁₅ πN resonance around 2 GeV in mass and (b) the more probable dominance of the 1.9 GeV enhancement seen in π⁺p → Σ⁺ (1385)K⁺ by P₃₃ and P₃₁ rather than F₃₇ or F₃₅ resonances.
