Abstract: | We propose an SU(5) model for the new heavy mesons, with a charge fancy quark in addition to a charge charmed quark. Besides interpreting the two narrow vector mesons J/Ψ and Ψ′ as c and f 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 between J/Ψ and Ψ ′, with suppressed radiative decays , (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 N reactions, (v) a possible heavy lepton. |
