Research output: Contribution to journalArticlepeer-review

Using SU(6)W symmetry in its l-broken form we find that the newly reported relative signs of πN → ρ{variant}N resonant amplitudes seem to indicate a universal "SU (6)W-like" preference for all observed multiplets. Since the corresponding πN → πΔ phases favour an "anti-SU(6)W" solution for the 70, LP = 1- multiplet the l-broken SU (6)W model now faces a serious contradiction.
