论文摘要
我们在QQQ系统的第一个径向和角度激发的库仑QCD的现场理论模型中介绍了一个新计算。这项研究的传统动机是，在最低层的频谱中缺乏风味的单线是颜色自由程度的直接结果。 （该计算是用解剖Baryons Delta（1232）和Omega（1672）测试的。）我们还分析了具有最简单有效的Lagrangians的各种质量的味道单重男体的衰减分支。
We present a new computation in a field-theoretical model of Coulomb gauge QCD of the first radial and angular excitations of a qqq system in a SU(3) flavor singlet state, Lambda_S. The traditional motivation for the study is that the absence of flavor singlets in the lowest-lying spectrum is a direct consequence of the color degree of freedom. (The calculation is tested with decuplet baryons Delta(1232) and Omega(1672).) We also analyze decay branching fractions of the flavor singlet baryon for various masses with the simplest effective Lagrangians.
