Abstract
In this work, the decays of mesons to a charmonium state and a pair are carefully investigated in the perturbative QCD approach. Following the latest fit from the LHCb experiment, we restrict ourselves to the case where the produced pair interact in isospin zero , , and wave resonances in the kinematically allowed mass window. Besides the dominant contributions of the resonance in the -wave and in the -wave, other resonant structures in the high mass region as well as the -wave components are also included. The invariant mass spectra for most of the resonances in the decay are well reproduced. The obtained three-body decay branching ratios can reach the order of , which seem to be accessible in the near future experiments. The associated polarization fractions of those vector-vector and vector-tensor modes are also predicted, which are compared with the existing data from LHCb Collaboration.
