Abstract

We propose assignment of the new

ψ

particles in an SU(4) symmetry scheme, incorporating SU(3) and a new additive quantum number, paracharge

Z

. Anomalous currents are introduced to account for the production and decays of these particles. Two more rather broad resonances at around 4.3 and 5.0 (±0.2) GeV are expected in the

e^{+} e^{-}

annihilation, one of which has recently been reported (at 4.15 GeV).
