论文摘要
已经考虑了具有旋转3/2的粒子的无冗余组件的相对论波动方程。为了显示新颖性，给出了与自旋s = 3/2场的已知方程进行比较。因此，给出了对带自旋s = 3/2的粒子的相对论波方程的简要回顾。在我们的方程式中，粒子 - 安装粒子双线的波函数仅具有8个成分。考虑因素是在相对论量子力学的层面和局部场理论级别进行的。提出了扩展的折叠 - wouthuysen变换，该变换赋予了这两个级别之间的操作员链接。
Relativistic wave equation of motion without redundant components for the particle having spin 3/2 has been considered. In order to show the newness a comparison with the known equations for the spin s=3/2 field is given. Therefore, the brief review of the relativistic wave equations for the particle with spin s=3/2 is given. In our equation the wave function for the particle-antiparticle doublet has only 8 components. The consideration is carried out both at the level of relativistic quantum mechanics and at the level of local field theory. The extended Foldy--Wouthuysen transformation, which gives the operator link between these two levels is suggested.
