我们用甚狭义相对论（VSR）来描述自然界，其时空对称性是庞加莱群的某些真子群。这些子群包含时空平移以及洛伦兹群的至少一个双参数子群，该子群同构于由K（x）+ J（y）和K（y）- J（x）生成的子群。我们发现，VSR意味着狭义相对论（SR）在局域量子场论或守恒的背景下。如果没有这两个附加的假设，VSR提供了一个SR的模拟，其中洛伦兹不变性的大部分结果仍然完全或基本上完好无损，许多敏感的搜索偏离洛伦兹不变性必须失败。几个可行的实验进行了讨论，其中违反VSR的影响可能是可检测的。
By very special relativity (VSR) we mean descriptions of nature whose space-time symmetries are certain proper subgroups of the Poincaré group. These subgroups contain space-time translations together with at least a two-parameter subgroup of the Lorentz group isomorphic to that generated by K(x) + J(y) and K(y)- J(x). We find that VSR implies special relativity (SR) in the context of local quantum field theory or of conservation. Absent both of these added hypotheses, VSR provides a simulacrum of SR for which most of the consequences of Lorentz invariance remain wholly or essentially intact, and for which many sensitive searches for departures from Lorentz invariance must fail. Several feasible experiments are discussed for which Lorentz-violating effects in VSR may be detectable.
