中微子速度实验对Horava-Lifshitz引力的约束

Constraining Horava-Lifshitz gravity from neutrino speed experiments

Emmanuel N. Saridakis

摘要:

我们利用OPERA和ICARUS中微子速度实验的结果来约束Horava-Lifshitz引力,这些实验表明中微子是光粒子,并考察了费米子在地球引力场中的传播.特别是,调查狄拉克方程的球形解决方案的理论,我们发现,中微子感觉到一个有效的度量,他们可能会传播superluminally。因此,要求没有超光速或亚光速运动,我们限制了理论的参数。虽然排除的参数区域很窄,我们发现,细致平衡的情况下,在排除的区域。

英文摘要:

We constrain Horava-Lifshitz gravity using the results of OPERA and ICARUS neutrino speed experiments, which show that neutrinos are luminal particles, examining the fermion propagation in the earth's gravitational field. In particular, investigating the Dirac equation in the spherical solutions of the theory, we find that the neutrinos feel an effective metric with respect to which they might propagate superluminally. Therefore, demanding not to have superluminal or subluminal motion we constrain the parameters of the theory. Although the excluded parameter regions are very narrow, we find that the detailed balance case lies in the excluded region.
