N2 - We propose an SU(5) model for the new heavy mesons, with a charge -1 3 fancy quark in addition to a charge +2 3 charmed quark. Besides interpreting the two narrow vector mesons J/Ψ and Ψ′ as cc and ff bound states and accounting for present data in a natural way, the model has (i) three new fancy vector mesons in addition to the charmed ones of the SU (4) model, (ii) at most two new C = P = + mesons (cc, 3 PJ, J = 0, 1) between J/Ψ and Ψ ′, with suppressed radiative decays Ψ′ → 3PJ + γ, (iii) a state near 4.6 GeV in e+e-, decaying mostly to fancy mesons if it is broad or perhaps charmed mesons if it is narrow, (iv) V + A weak currents and a large anomaly in νN reactions, (v) a possible heavy lepton.
