英文摘要We investigate the long distance contribution via charmed hadron loops in the processes eta(c), chi(c0) and h(c) decaying to baryon-anti-baryon pairs, which are supposed to be highly suppressed by the helicity selection rule as a consequence of the perturbative QCD framework. With an effective Lagrangian method, our estimation result indicates that such hadron loops play an important role in these hadronic decays. It is a further test of the evading mechanism for the helicity selection rule in charmonium baryon-anti-baryon decays.
