Search for Vector Charmonium(-Like) States in the e+e-→ηJ/ψ Line Shape
The cross section of e+e-→ηJ/ψ has been measured by BESIII and Belle experiments. Fit to the e+e-→ηJ/ψ line shape, the resonant structures are evident. The parameters for the three resonant structures are M1=(3980±17±7) MeV/c2, Γ1=(104±32±13) MeV; M2=(4219±5±4) MeV/c2, Γ2=(63±9±3) MeV; and M3=(4401±...
