Mass levels of some elementary particles

The structure and mass levels of some elementary particles are presented. A non-relativistic bound state model has been used to describe the J \ψ and ψ' particles. The order of levels, 1S - 2P - 2S, as observed in the ψ, X, ψ’ spectroscopy is generally assumed. We introduce as interaction potential a confining potential (Vc) in combination with a Coulomb-like potential -g^2/r to try to prove that the 2S level is above the 2P level. Our result shows that the order of levels is what we believe it to be: IS - 2P - 2S.
