相对论性超光速中微子

Relativistic Superluminal Neutrinos

Alex Kehagias

摘要:

我们提出了一个可能的解决方案的报告OPERA异常的中微子的速度,基于的想法,这是一个本地的标量场引起的地球来源。标量与中微子的耦合有效地改变了中微子传播的背景度规,导致了超发光。耦合强度由新的质量标度设置,该质量标度应在$1\, {\rm TeV}$,以解释OPERA异常。此外,如果这种情况是有效的,中微子的速度取决于发射点和探测点之间的基线距离,这样,超光速信号就变成了亚光速信号,基线距离大致大于地球半径。

英文摘要:

We present a possible solution to the reported OPERA anomaly for the speed of neutrinos, based on the idea that it is a local effect caused by a scalar field sourced by the earth. The coupling of the scalar to neutrinos effectively changes the background metric where neutrinos propagate, leading to superluminality. The strength of the coupling is set by a new mass scale, which should be at $1\, {\rm TeV}$ to account for the OPERA anomaly. Moreover, if this scenario is valid, the neutrino velocity depends on the baseline distance between the emission and detection points in such a way that superluminal signals turn to subluminal ones for baseline distances roughly larger than the earth radius.
