Abstract

The reaction e⁺e^- →e⁺e^- ηπ⁰π⁰→e⁺e^- 6γ has been analysed using the full data sample taken with the Crystal Ball detector at the DORIS II storage ring at DESY. The ηπ⁰π⁰ invariant mass spectrum is dominated by the η', for which we determine the radiative width Γγγ(η') to be (4.5±0.3±0.5)keV. Near 1.9 GeV/c² we observe a second enhancement in the ηπ⁰π⁰ mass distribution. Assuming that these events are created by the production and subsequent decay of a wide resonance X(1900), we have investigated the decay modes, the invariant mass distributions of the ηπ⁰ and π⁰π⁰ subsystems and the angular distributions of the final state mesons. We find that the data is best described by J^PC=2^∓. For this J^P assignment the resonance parameters are Γ_γγ(X) BR(X→ηππ)=(0.95±0.27±0.20) keV Γ_tot (X)=(221±92±44)MeV, and M(X)=(1881±32±40) MeV/c².
