【摘要】 本文讨论了带电点粒子的正常自旋磁矩,导出在最小电磁耦合时自旋S的点粒子的g因子普遍为 g(S)=1/S。对于非最小电磁耦合的情形,讨论了SU(2)×U(1)电弱统一理论中的W粒子,给出W粒子的g=2。最后对所得结果进行了讨论。更多还原

【Abstract】 In this paper, the normal spin magnetic moments of charged particles are discussed. The g-factor of point particle for spin S with minimun electro-magnetic coupling is derived. For cases other than minimun electro-magnetic coupling, W particle in SU(2) U(1) electro-weak unified theory is discussed and g = 2 for W particle is obtained. Finally all obtained results are discussed briefly.更多还原
