Title: X(1576) and the final state interaction effect

Abstract

We study whether the broad peak X(1576) observed by BES Collaboration arises from the final state interaction effect of {rho}(1450 1700) decays. The interference effect could produce an enhancement around 1540 MeV in the K{sup +}K{sup -} spectrum with typical interference phases. However, the branching ratio B[J/{psi}{yields}{pi}{sup 0}{rho}(1450 1700)]{center_dot}B[{rho}(1450 1700){yields}K{sup +}K{sup -}] from the final state interaction effect is far less than the experimental data.
