摘要

本文讨论了KM3NeT对KM3-230213A超高能量事件在线性\(n=1\)和二次\(n=2\) LIV情况下对超光速中微子洛伦兹不变量破坏（LIV）参数的约束。假设事件的起源是河外的，我们从没有中微子分裂得到了LIV质量尺度\(\Lambda _{n=1} = 1.1 \times 10^{30}\, \text{ GeV }\)和\(\Lambda _{n=2} = 1.1 \times 10^{19}\, \text{ GeV }\)的约束。

Ultra-high-energy event KM3-230213A constraints on Lorentz Invariance Violation in neutrino sector

We discuss the constraints on superluminal neutrino Lorentz Invariance Violation (LIV) parameters from the observation of the ultra-high-energy event KM3-230213A by the KM3NeT collaboration in cases of linear \(n=1\) and quadratic \(n=2\) LIV scenarios. Assuming extragalactic origin of the event, we obtain the constraints on LIV mass scale \(\Lambda _{n=1} = 1.1 \times 10^{30}\, \text{ GeV }\) and \(\Lambda _{n=2} = 1.1 \times 10^{19}\, \text{ GeV }\) from the absence of neutrino splitting.
