二阶超越狭义相对论

Beyond Special Relativity at second order

J. M. Carmona, J. L. Cortes, J. J. Relancio

摘要:

由高能标度$M$参数化的狭义相对论的通用非线性变形的研究(其在物理学修订版D86,084032(2012)中的$M$中以一阶进行)被扩展到二阶。这可以通过线性变换的动量变量的(“广义”)变量变化来系统地完成。我们讨论了变量变化的意义上的不同观点,获得修改后的组成定律和洛伦兹变换在二阶的系数,并制定出如何$κ$ -庞加莱,在文献中最常用的例子,是作为一个特殊的情况下,这里暴露的通用框架再现。

英文摘要:

The study of generic, non-linear, deformations of Special Relativity parametrized by a high-energy scale $M$, which was carried out at first order in $M$ in Phys.Rev. D86, 084032 (2012), is extended to second order. This can be done systematically through a ('generalized') change of variables from momentum variables that transform linearly. We discuss the different perspectives on the meaning of the change of variables, obtain the coefficients of modified composition laws and Lorentz transformations at second order, and work out how $κ$-Poincaré, the most commonly used example in the literature, is reproduced as a particular case of the generic framework exposed here.
