超光速中微子的OPERA结果解释

Interpreting OPERA results on superluminal neutrino

Gian F. Giudice, Sergey Sibiryakov, Alessandro Strumia

摘要:

OPERA声称发现了中微子的超光速传播。我们分析了这一主张与以前的狭义相对论测试的一致性。我们发现,从SN 1987 a和中微子振荡的信息协调OPERA测量需要严格的条件。中微子的超光速极限速度必须是几乎与味道无关的,必须在低能区急剧下降,并且它的能量依赖性必须偏离简单的幂律。我们构建说明性的模型,满足这些条件,通过引入洛伦兹破坏轻不育中微子的部门。我们指出,相当一般地,电弱量子校正超光速中微子性质的信息转移到洛伦兹违反在电子和μ子部门,在明显的冲突与实验数据。

英文摘要:

OPERA has claimed the discovery of superluminal propagation of neutrinos. We analyze the consistency of this claim with previous tests of special relativity. We find that reconciling the OPERA measurement with information from SN1987a and from neutrino oscillations requires stringent conditions. The superluminal limit velocity of neutrinos must be nearly flavor independent, must decrease steeply in the low-energy domain, and its energy dependence must depart from a simple power law. We construct illustrative models that satisfy these conditions, by introducing Lorentz violation in a sector with light sterile neutrinos. We point out that, quite generically, electroweak quantum corrections transfer the information of superluminal neutrino properties into Lorentz violations in the electron and muon sector, in apparent conflict with experimental data.
