在屏蔽色约束的成分夸克模型的框架下，利用动量空间中的非相对论和半相对论Faddeev方程研究了非奇异重子谱。结果表明，高能重子谱可以得到定性的描述，特别是对于激发能为1-1.5GeV的态。与线性限制势相比，在屏蔽色限制下，非相对论和半相对论方法之间的差异变得更小。
In the frame of the constituent quark model with screened color confinement, non-strange baryon spectra are studied by using non-relativistic and semi-relativistic Faddeev equations in momentum space. The results show that a qualitative description of the high-energy baryon spectra can be obtained, especially for states at excitation energies from 1 to 1.5 GeV. Compared with the linear confinement potential, the discrepancy between non-relativistic and semi-relativistic approaches becomes smaller in the present model with screened color confinement.
