Description

Utilizing the Jost-function approach, we analyze all the existing data for p anti p spectrum up to excess energy of 100 MeV from J/ψ, ψ' decays to γ, π, η or ωp anti p. For the potential used in this analysis, both the chiral potential constructed by us previously and the Juelich model A(OBE) have been considered. We have shown that the near-threshold spectrum can be described by our treatment of the final state interaction effect.
