Abstract
We present evidence, from a study of multihadronic final states produced in annihilation at center-of-mass energies between 3.90 and 4.60 GeV, for the production of a new neutral state with mass 1865±15 MeV/ and decay width less than 40 MeV/ that decays to and . The recoil-mass spectrum for this state suggests that it is produced only in association with systems of comparable or larger mass.
