Comment on the X(3915) nonstandard hadron candidate
I review the experimental evidence for the X(3915), the candidate nonstandard meson associated with ωJ/ψ resonance-like peaks in B → KωJ/ψ and γγ → ωJ/ψ near M(ωJ/ψ) = 3920 MeV, and address the conjecture that it can be identified as the χ′c2, the radial excitation of the χc2 charmonium state. Since...
