Abstract
Results are presented from a hydrogen-bubble-chamber study of the final states and , where M represents a neutral boson state of mass . The proton was identified by ionization for all events in the sample. Production of , , and mesons with decays into all neutral particles is observed in the final state. Peaks are observed in the spectrum at 1080 and 1310 MeV. The higher-mass peak has mass 1306±8 MeV and width MeV and is identified as the . The branching ratio for has been measured as (18±7)%. There is no evidence for a 980-MeV enhancement. Data on the final state show evidence for and production.
