Abstract
We assign ψ(3695) to an exotic meson cc(pp+nn) and ψ(3105) to a vector meson cc, respectively. Then we can explain naturally two facts: 1) ψ(3695) decays strongly to ψ(3105) + 2π and 2) there is very little ψ(3695) production compared with ψ(3105) production in pN scattering at Brookhaven. In this model we expect two broad resonances at 3.7 ∼4.1 GeV and at ∼4.1 GeV. We also predict another resonance at ∼6.2 GeV, which will be a sharp resonance if the mass is smaller than twice the mass of the lowest mass state of cc.
