最近,Cohen和Mackhow [A.G. Cohen,S.L.《物理学评论》(Phys. Rev. Lett.)107(2011)181803]指出OPERA报告的超光速中微子会通过类切伦科夫过程迅速失去能量。如果狭义相对论原理在任何坐标系中成立,而不是在一个优选坐标系中被违反,那么超光速粒子的切伦科夫式过程将被禁止。我们已经提出,芬斯勒狭义相对论可以解释中微子超发光的数据(arXiv:1110.6673 [hep-ph])。芬斯勒狭义相对论保持了狭义相对论的基本原理,在与因果关系相一致的同时,也包含了一个优选方向。在这封信中,我们证明了能量动量守恒是保持和能量动量是很好地定义在芬斯勒狭义相对论。类切伦科夫过程在芬斯勒狭义相对论中是被禁止的。因此,超光速中微子在远距离传播时不会损失能量。
Recently, Cohen and Glashow [A.G. Cohen, S.L. Glashow, Phys. Rev. Lett. 107 (2011) 181803] pointed out that the superluminal neutrinos reported by the OPERA would lose their energy rapidly via the Cherenkov-like process. The Cherenkov-like process for the superluminal particles would be forbidden if the principle of special relativity holds in any frame instead violated with a preferred frame. We have proposed that the Finslerian special relativity could account for the data of the neutrino superluminality (arXiv:1110.6673 [hep-ph]). The Finslerian special relativity preserves the principle of special relativity and involves a preferred direction while consists with the causality. In this Letter, we prove that the energy–momentum conservation is preserved and the energy–momentum is well defined in Finslerian special relativity. The Cherenkov-like process is forbidden in the Finslerian special relativity. Thus, the superluminal neutrinos would not lose energy in their distant propagation.
