Mass of the psi(3095) as an N anti N resonance

1975 
Guided by a suggestion that the psi(3095) is an N anti N resonance, and using the basis states of a previously-published light-quark model, we ''calculate'' the mass of the psi as 3105/sub -15//sup +5//MeV. The appearance of a narrow-width meson resonance at this mass value is consistent with a systematic formalism that was devised to generate the observed spectrum of lower- mass narrow-width meson resonances. However, the width of the psi is narrower by a factor of $alpha$$sup -1$=137 than we would have anticipated on the basis of the light-quark model. The psi'(3684) resonance also fits into this formalism, but the mass of the psi' has a larger calculational uncertainty since it is above the N anti NN anti N threshold. (AIP)
