Abstract: We propose a new quark model for the hadron spectrum. It consists of six quarks - the usual triplet and a new antitriplet of heavy quarks, with electric charges +23, +23,−13. The ψ particles are bound states of heavy qq pairs. Among many other predictions we find that R = 5 in e+e− scattering and Γ (ψ→e+e−): Γ(ψ′→e+e− = 2:1. The model naturally forbids neutral |ΔS|=1 weak currents and predicts a spectrum of heavy mesons and baryons.
