Multihadronic decays and partial widths of the J/Ψ (3100) resonance produced in e+e− annihilation at adone

The reactions e+e−→ hadrons and e+e+e−→e+e− have been studied at the J/gY (3100) resonance). The relative weights of the topological cross sections for fixed charged multiplicity are σ2=(32±5)%, σ4=(49±8)%, σ6=(18±3)%, and σ8=(1±0.6)%. The average pion multiplicities are 〈nch〉=3.8±0.3 and 〈nπo〉=3.1±0.8. The decay widths are Γe=(4.6±0.8) keV, Γh=(59±24) keV, and Γ=(68±26) keV.
