标题： Towards a Unified Description of the Baryon Spectrum and the Baryon-Baryon Interaction within a Potential Model Scheme

摘要： 我们通过在超球谐方法中求解三个夸克系统的薛定谔方程，研究核子和$\Delta$谱的低能部分。 所考虑的夸克-夸克哈密顿量除了通常的一胶子交换外，还包括由手征对称性破缺产生的介子和σ介子交换。 这种夸克-夸克势能在共振组方法计算中，再现了核子-核子散射相移和氘核的性质。 得到的重子谱非常合理，所得波函数与两重子系统中使用的假设一致。 显示英文摘要

摘要： We study the low energy part of the nucleon and $\Delta$ spectra by solving the Schr\"{o}dinger equation for the three-quark system in the hyperspherical harmonic approach. The quark-quark hamiltonian considered includes, besides the usual one-gluon exchange, pion and sigma exchanges generated by the chiral symmetry breaking. This quark-quark potential reproduces, in a Resonating Group Method calculation, the nucleon-nucleon scattering phase shifts and the deuteron properties. The baryonic spectrum obtained is quite reasonable and the resulting wave function is consistent with the ansatz used in the two baryon system.
