Phys. Rev. D 72, 074001 (2005) [6 pages]Coherent study of χc0,2→VV, PP and SSReceived 6 August 2005; published 4 October 2005 We investigate the decays of χc0,2 into vector meson pairs (VV), pseudoscalar pairs (PP), and scalar pairs (SS) in a general factorization scheme. The purpose is to clarify the role played by the OZI-rule violations and SU(3) flavour breakings in the decay transitions, and their correlations with the final-state meson wavefunctions. For χc0,2→VV and PP, we obtain an overall self-contained description of the experimental data. Applying this factorization to χc0→f0if0j, where i,j=1,2,3 denotes f0(1710), f0(1500) and f0(1370), respectively, we find that specific patterns will arise from the model predictions for the decay branching ratio magnitudes, and useful information about the structure of those three scalars can be abstracted. © 2005 The American Physical Society URL:
