中微子速度的振荡

Oscillations of neutrino velocity

Branislav Sazdović, Milovan Vasilić

摘要:

本文考虑中微子速度的量子测量问题。我们证明,中微子味振荡总是伴随着中微子速度的振荡。特别是,自由运动的中微子的速度被证明周期性地超过光速。不幸的是,超光速效应太小,无法通过实验检测到。中微子速度与中微子波包的能量、大小和形状有关。由于最近的实验误差很大,这些依赖性仍然不明显。最后,我们证明了最近关于超光速中微子在飞行过程中会释放能量的说法是不正确的。相反,我们的公式提出了沿中微子轨道的近似能量守恒。所有这些结果都是在不违反狭义相对论的情况下得到的。

英文摘要:

In this paper, we consider the problem of quantum measurement of neutrino velocity. We show, that the well known neutrino flavor oscillations are always accompanied by the oscillations of neutrino velocity. In particular, the velocity of a freely moving neutrino is demonstrated to periodically exceed the speed of light. Unfortunately, the superluminal effect turns out to be too small to be experimentally detected. It is also shown that neutrino velocity significantly depends on the energy, size and shape of the neutrino wave packet. Owing to the big experimental error of the recent experiments, these dependences remained unnoticeable. Finally, we have shown that the recent claims that superluminal neutrinos should loose energy during their flight is not true. Instead, our formula suggests the approximate conservation of energy along neutrino trajectory. All these results have been obtained without violation of special theory of relativity.
