Abstract
Possible interpretations for the are discussed in accordance with new data from Baltrusaitis et al., Aston et al., and Binon et al., and it is argued that the is likely to be a baryonium state, which couples strongly to and decays to , , , , , and , via quark rearrangement, and also to , , and via quark annihilation, and therefore has a narrow width. A possible hybrid state, which can decay to , , and other mesons, is also suggested.
