组分夸克模型下研究高次分波的核子-核子散射

摘要

By using the chiral quark model and quark delocalization colour screening model, the phase shifts of NN scattering for high partial waves are studied. The results of these two models are almost equivalent. None of the quark models used have found any resonance-like structure in 3F2,3F3,3F4 and 3H4 partial waves.%在手征夸克模型和夸克蜕定域色屏蔽模型框架下,利用共振群方法研究高次分波的核子-核子散射相移,两个模型结果基本一致,且与实验相符.在3F2、3F3、3F4和3H4分波中,两个模型都没有找到任何共振态.
