Description
We study whether the broad peak X(1576) observed by BES Collaboration arises from the final state interaction effect of ρ(1450 1700) decays. The interference effect could produce an enhancement around 1540 MeV in the K+K- spectrum with typical interference phases. However, the branching ratio B[J/ψ→π0ρ(1450 1700)]·B[ρ(1450 1700)→K+K-] from the final state interaction effect is far less than the experimental data
