Abstract：
Based on a systematic investigation of J/ψ(ψ´)→VP, where V and P stand for light vector and pseudoscalar mesons, we identify the role played by the electromagnetic (EM) transitions and intermediate meson loop transitions, which are essential ingredients for understanding the J/ψ and ψ´ couplings to VP. We show that on the one hand, the EM transitions have relatively larger interferences in ψ´→ρπ and K^*K+c.c. as explicitly shown by vector meson dominance (VMD). On the other hand, the strong decay of ψ´ receives relatively larger destructive interferences from the intermediate meson loop transitions. By identifying these mechanisms in an overall study of J/ψ(ψ´)→VP, we provide a coherent understanding of the so-called ``ρπ puzzle".
