Studying the decay mode of the J/{psi} into a vector meson and a tensor resonance

The decay mode of the J/{psi} into a vector meson and a tensor resonance is presented. The tensor resonances are considered as dynamically generated states from the vector meson-vector meson interaction provided by the hidden gauge formalism upon unitarization in coupled channels. The couplings of the resonances to the pairs of vector-vector building blocks were evaluated in a previous work. Four ratios of partial decay widths are evaluated using one parameter and compared with experimental data including BES collaboration. The theoretical results are compatible with present experimental data.
