具有非中心谐振子势的重子能级和尺寸的计算

Calculation of the energy levels and sizes of baryons with a noncentral harmonic potential

Mario Everaldo de Souza

摘要:

本文认为重子中任意两个夸克之间的有效相互作用可以用一个简谐势近似描述。此外,它是利用非相对论近似。首先在笛卡尔坐标系下求解该问题,以求出不考虑角动量的能级,然后在极坐标系下求解该问题,以考虑能级的角动量。计算中唯一使用的参数是夸克的组成质量。通过对这两种解的比较,我们描述了几乎所有重子能级的能量和相应的角动量(和宇称)。与实验数据的一致性令人印象深刻。在笛卡尔坐标系中的解决方案也产生了一些非常重要的数字的重子的大小和谐振子常数,这显然是与禁闭。

英文摘要:

It is considered that the effective interaction between any two quarks in a baryon can be approximately described by a simple harmonic potential. Also, it is made use of the nonrelativistic approximation. The problem is firstly solved in Cartesian coordinates in order to find the energy levels irrespective of their angular momenta and then it is also solved in polar cilindrical coordinates for taking into account the angular momenta of the levels. The only parameters used in the calculation are the constituent masses of quarks. By making a comparison between the two solutions the energies and the corresponding angular momenta (and parity) of almost all baryon levels are described. The agreement with the experimental data is quite impressive. The solution in Cartesian coordinates also produces some very important figures for the sizes of baryons and for the harmonic oscillator constant which is clearly related to confinement.
