摘　　要：实验上越来越多的重子能谱被精确地测出来,人们可以通过理论数据和实验数据的对比来更加准确地研究夸克与夸克间的相互作用形式。文章在夸克势模型的基础下研究了核子和Δ粒子。基本途径是将重子看成三体系统,通过在不同空间的对称性构造出全反对称的波函数。夸克间的相互作用势在短程区取单胶子交换势,长程区取矢量禁闭和线性禁闭的混合,然后求解出三体系统的薛定谔方程,得到相应的能谱。More and more baryon spectrum are measured accurately in experiments.People can study the interaction between quarks more accurately by comparing theoretical data with experimental data.Nucleons and particles are studied based on the quark potential model.The basic approach is to regard baryons as three-body systems and construct wave functions that are all opposed by symmetry in different spaces.The interaction potential between quarks takes the single gluon exchange potential in the short-range region and the mixture of vector confinement and linear confinement in the long-range region.Then,we can get baryon spectrum by solve schrodinger equation of three-body problem.
