非常狭义相对论与洛伦兹违背理论

Very Special Relativity and Lorentz Violating Theories

Jorge Alfaro, Victor O. Rivelles

摘要:

非常狭义相对论(VSR)保持了狭义相对论的主要特征,但破坏了转动不变性。它不能被视为自然界的基本对称,因为许多观察到的现象依赖于洛伦兹助推的存在。然而,在洛伦兹破坏理论的范围内,它可以发挥作用,因为它以非常温和的方式破坏洛伦兹对称性。在这种情况下,当VSR条款纳入洛伦兹不变理论几种可能性是允许的。为了系统地产生这些术语,我们从VSR中的自旋粒子的配方开始。然后,它被最小程度地耦合到电磁场,并添加旋磁因子以产生磁矩。为了分析托马斯进动中的VSR效应,本文提出了一个自旋矢量。然后发现VSR对决定自旋进动角速度的方程的贡献。

英文摘要:

Very special relativity (VSR) keeps the main features of special relativity but breaks rotational invariance. It can not be regarded as a fundamental symmetry of nature because many observed phenomena depend on the existence of Lorentz boosts. However, within the scope of Lorentz violating theories it can have a role since it is breaking Lorentz symmetry in a very mild way. In this context, when VSR terms are incorporated in a Lorentz invariant theory several possibilities are allowed. In order to generate such terms systematically we start with a formulation for a spinning particle in VSR. It is then coupled minimally to the electromagnetic field and a gyromagnetic factor is added to give rise to a magnetic moment. In order to analyze the effects of VSR in Thomas precession a spin vector is then proposed in terms of the spinning particle variables. It is then found the VSR contributions to the equation which determines the spin precession angular velocity.
