Conventional Hadronic Model of the New Particles at 3.1 and 3.7 GeV

We suggest that $\psi \mathrm{}\left(3.1\right)\mathrm{}$ and $\psi \mathrm{}\left(3.7\right)\mathrm{}$ are a bound state and resonance, respectively, of the ${\Omega }^{-}{\overline{\Omega }}^{+}$ system, with decay of $\psi \mathrm{}\left(3.1\right)\mathrm{}$ predominantly into three $\lambda \overline{\lambda }$ mesons. Conventional hadronic couplings may then be adopted, with the small $\psi \mathrm{}\left(3.1\right)\mathrm{}$ width an automatic consequence of the bound-state nature and the small $Q$ values of these decays. Branching ratios of $\psi \mathrm{}\left(3.1\right)\mathrm{}$ and $\psi \mathrm{}\left(3.7\right)\mathrm{}$ are calculated and crucial tests of the model pointed out.
