OBSERVATION IN e+e- ANNIHILATION OF A NARROW STATE - AT 1865 MeV/c2 DECAYING TO K?I and KITIT~T* cp

Abstract

We present evidence,from a study of multihadronic'final states produced in e+eannihilation at center-of-mass energies between 3.90 GeV and 4.60 GeV,for the production of a new neutral state with mass 1865 + 15 MeV/c: an$ -2 T decay width less than 40 MeV/c2 that decays to K v -T-r and K r 71 r . The recoil mass spectrum for this state suggests that it is… (More)
