| 英文摘要 | Based on a systematic investigation of j/psi(psi') -> 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/psi and psi' couplings to vp. we show that on the one hand, the em transitions have relatively larger interferences in psi' -> rho pi and k*(k) over bar + c.c. as explicitly shown by vector meson dominance (vmd). on the other hand, the strong decay of psi' receives relatively larger destructive interferences from the intermediate meson loop transitions. by identifying these mechanisms in an overall study of j/psi(psi') -> vp, we provide a coherent, understanding of the so-called "rho pi puzzle". |
