Abstract: (APS)

If the recently discovered Y* state is related to the T=32, J=32 resonance in πp scattering, global symmetry considerations should become relevant. In this paper, global symmetry is discussed with a view to understanding its group structure. Also discussed is a possibility of reconciling the conflict, pointed out by Pais, between certain experimental results and global symmetry. The partial widths of the Y* state are calculated and also those of the companion excited states Z* and Ξ*. A generalization of the quantum number G is discussed.
