Description
An exotic meson, the π1(1400) with JPC=1-+, has been seen to decay into a p-wave ηπ system. If this decay conserves flavor SU(3), then it can be shown that this exotic meson must be a four-quark state (qq+qq) belonging to a flavor 10+10 representation of SU(3). In contrast, the π1(1600) with a substantial decay mode into η'π is likely to be a member of a flavor octet. (orig.)
