摘要：

We study phenomenologically the invariant mass spectra of scalar dipion states produced in cascade decays of excited Y and psi, and J/psi decays into light vector mesons. The dipion production amplitude is given as a product in the Born term and an effective scalar form factor written in terms of a unitarized chiral theory. The model reproduces the experimental mass spectra very well.
