本文报道了用色动力学方法对夸克模型中重子耦合进行广泛分析的结果。从分析中出现的振幅解决了“丢失"重子共振的问题，表明大量的状态基本上与分波分析解耦;那些保留下来的共振在质量和衰变振幅上都与观测到的状态有显著的对应关系。
This paper reports on the results of an extensive analysis of baryon couplings in a quark model with chromodynamics. The amplitudes which emerge from the analysis resolve the problem of ''missing'' baryon resonances by showing that a very large number of states essentially decouple from the partial-wave analyses; those resonances which remain are in remarkable correspondence to the observed states in both their masses and decay amplitudes.
