Abstract
We make predictions for the ratios of branching fractions of and decays into and the scalar mesons , or tensor mesons , , . The theoretical approach is based on results of chiral unitary theory where these resonances are shown to be generated from the vector meson–vector meson interaction. Eight independent ratios can be predicted, and comparison is made with the recent data on decay into versus the decay into .
