AB We study the role of the f(1)(1285) resonance in the decays of J/psi -> phi(K) over barK* and J/psi -> f(1) (1285). The theoretical approach is based on the results of chiral unitary theory where the f1(1285) resonance is dynamically generated from the K* (K) over bar -c.c. interaction. In order to further test the dynamical nature of the f(1)(1285) state, we investigate the J/psi -> phi(K) over barK* decay close to the (K) over barK* threshold and make predictions for the ratio of the invariant mass distributions of the J/psi -> phi(K) over barK* decay and the J/psi -> phi f(1)(1285) partial decay width with all the parameters of the mechanism fixed in previous studies. The results can be tested in future experiments and therefore offer new clues on the nature of the f(1) (1285) state.
