中微子速度异常作为洛伦兹破坏的信号

Neutrino speed anomaly as signal of Lorentz violation

Zhou Lingli, Bo-Qiang Ma

摘要:

本文结合ICARUS实验和CNGS合作的最新数据,对中微子速度反常问题进行了重新分析。我们在标准模型补充(SMS)的新框架下考察了Lorentz破坏对中微子速度的影响,发现Lorentz破坏参数的约束比OPERA报告中的强至少一个数量级.结合其他唯象的考虑,对中微子的洛伦兹破坏提出了更严格的限制。

英文摘要:

We make a reanalysis on the issue of neutrino speed anomaly by taking into account the newly reported data from the ICARUS experiment and other CNGS collaborations. We examine the consequence of the Lorentz violation on the neutrino speed in a new framework of standard model supplement (SMS), and find that the Lorentz violating parameters are constrained at least one order stronger than that of the earlier OPERA report. The combination with other phenomenological considerations puts more stringent constraints on the Lorentz violation of neutrinos.
