三体相互作用与重子谱

三体相互作用与重子谱 THREE BODY INTERACTION AND BARYON SPECTRUM 何裕金 He Yujin 1 first-author 刘觉平 Liu Jueping 1 武汉大学物理学系 武汉大学物理学系 Department of Physics,Wuhan University Department of Physics,Wuhan University 计算了三体相互作用势在ＳＵ（６）对称态中的平均值，研究了三体相互作用势对重子谱的影响．所得到的能谱与实验符合得较好，表明三体相互作用势的影响是不能忽略的． The expectation values of the three body potential in SU（6） symmetric states have been calculated,and the correction of the three body potential to the baryon spectrum is studied.The obtained spectrum well agrees with the experiments,which shows that the three body potential can’t be neglected.
