论文摘要
提出了通过库仑样染色体电位相互作用的两个相对论自旋1/2颗粒的复合系统的$ s $ factor的新重新调整。该分析是在相对论的准论方法的框架中，基于相对论配置表示中协变量量子场理论的大麻公式。考虑了伪尺度，矢量和伪造系统系统，并详细研究了阈值附近$ s $ factor的行为。也讨论了$ s $ factor的旋转依赖性。有人认为，在阈值下，旋转的贡献显着降低了sommerfeld效应，而在超偏移速度下，它们的作用会降低，而$ s $ factor的作用与无旋转系统基本相同。建立了新的和先前获得的s因子与任意质量的无旋转粒子与相对质量的相对论纺纱粒子之间的联系。
A new resummation of the $S$-factor of a composite system of two relativistic spin-1/2 particles of arbitrary masses interacting via a Coulomb-like chromodynamical potential is presented. The analysis is performed in the framework of a relativistic quasipotential approach based on the Hamiltonian formulation of the covariant quantum field theory in the relativistic configuration representation. The pseudoscalar, vector, and pseudovector systems are considered and the behaviour of the $S$-factor near the threshold and in the relativistic limit is investigated in detail. The spin dependence of the $S$-factors is discussed as well. It is argued that at the threshold the contribution of spins significantly reduces the Sommerfeld effect, while at ultrarelativistic velocities their role diminishes and the $S$-factor becomes basically the same as for the spinless systems. A connection between the new and previously obtained S-factors for spinless particles of arbitrary masses and for relativistic spinor particles of equal masses is established.
