Phys. Rev. Lett. 37, 255–259 (1976)Observation in e+e- Annihilation of a Narrow State at 1865 MeV/c2 Decaying to Kπ and KπππReceived 14 June 1975; published in the issue dated 2 August 1976 We present evidence, from a study of multihadronic final states produced in e+e- 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/c2 and decay width less than 40 MeV/c2 that decays to K±π∓ and K±π∓π±π∓. The recoil-mass spectrum for this state suggests that it is produced only in association with systems of comparable or larger mass. © 1976 The American Physical Society URL:
