由于强相互作用对跃迁振幅有很大的非微扰效应，因此与模型无关地描述粲介子的非轻子衰变是一项具有挑战性的任务。讨论了粲介子的Cabibbo非轻子衰变到包括η介子和η′介子在内的双赝标末态的两种不同味SU（3）基描述的等价性.
Model-independent description of nonleptonic decays of charmed mesons is a challenging task due to large nonperturbative effects of strong interactions on the transition amplitudes. We discuss the equivalence of two different flavor-SU (3)-based descriptions of Cabibbo-favored non-leptonic decays of charmed mesons to two-pseudoscalars final states including the η and η′ mesons.
