Description
Inclusive charged-pion spectra from p-bard annihilations at rest have been measured in a high-statistics experiment in search of broad states. Analysis of these spectra reveals an enhancement of the π- spectrum at 315 MeV/c. This may be interpreted as a production of a new state of mass 1485 MeV/c2 and width at most 200 MeV/c2 recoiling against the π-. This quasi two-body final state accounts for a large fraction of the p-barn annihilations
