Abstract

We point out that the intersection of the Berkeley-SLAC and Saclay signs of πN→ρ{variant}N resonant amplitudes are consistent with ℓ-broken SU(6)_W if both the 70, L^P = 1^-and 56, L^P = 2⁺ multiplets choose anti-SU(6)_W solutions. The symmetry scheme still fails in that the πN→πΔ relative signs require an SU(6)_W-like solution for the 56, L^P = 2⁺. This failure however now rests on a single incorrect sign prediction among all Nρ{variant} and Δπ amplitudes.
