| 英文摘要 | Based on the nonvalence quark-antiquark and gluon constituent structure of mesons we give a reasonable dynamical mechanism which can induce the hairpin diagram without violating the well-observed OZI rule. We calculate the hairpin amplitudes of D(o)-->KBAR(o)eta and KBAR(o)eta' normalized D(o)-->KBAR(o)pi(o) and have found that the hairpin diagram can give rise to substantial contributions to the decays where a meson with a SU(3) flavor singlet component is involved in the final state. In this scenario, we also obtain the branching ratio of D(o)-->KBAR(o)phi as 0.55% in comparison with the experimental data of 0.83%. |
