基本力结构的相对论约束
Relativistic Constraints on the Structure of Fundamental Forces
摘要：
证明了狭义相对论对基本力结构的约束。讨论了作用在基本粒子上的四维力与其四维速度的正交性。分析了与场相关的能量动量张量的意义。在此基础上，证明了洛伦兹力满足所有约束条件，而由标量势导出的力不满足所有约束条件。这种分析解释了戈尔茨坦，普尔和萨夫科的一般性讨论。
英文摘要：
It is proved that Special Relativity imposes constraints on the structure of fundamental forces. The orthogonality of the 4-force exerted on an elementary particle and its 4-velocity is discussed. The significance of the energy-momentum tensor associated with the field is analyzed. Relying on these issues, it is proved that the Lorentz force is consistent with all constraints whereas a force derived from a scalar potential does not satisfy all requirements. This analysis explains a general discussion of Goldstein, Poole and Safko.
