摘要:

先前的研究表明,具有狭义相对论变形的模型,具有依赖于能量但不依赖于光速的非局域效应,这些效应与非常高精度的观测相冲突。在最近的预印本中,有人声称这个结论是错误的。这一主张是通过写下修正的洛伦兹变换的表达式而提出的,而使用修正的洛伦兹变换并不能再现结果。我将在这里说明,无法重现结果并不是一种新的和改进的计算的结果,而是重复同样的计算,但做出的假设与产生原始情景的假设相冲突的结果。我将在这里解释任何一个假设的物理意义是什么,以及为什么最初的假设是有物理意义的假设。然后,我将进一步解释为什么即使做出不同的假设也不能消除问题,而只是转移问题,以及为什么Amelino-Camelia等人得出的界限是错误的。

英文摘要:

It was previously shown that models with deformations of special relativity that have an energy-dependent yet observer-independent speed of light suffer from nonlocal effects that are in conflict with observation to very high precision. In a recent preprint it has been claimed that this conclusion is false. This claim was made by writing down expressions for modified Lorentz-transformations the use of which does not reproduce the result. I will show here that the failure to reproduce the result is not a consequence of a novel and improved calculation, but a consequence of repeating the same calculation but making an assumption that is in conflict with the assumptions made to produce the original scenario. I will here explain what the physical meaning of either assumption is and why the original assumption is the physically meaningful one. I will then further explain why even making the differing assumption does not remove but merely shift the problem and why the bound derived by Amelino-Camelia et al is wrong.
