Based on the recent association of IceCube TeV and PeV neutrino events with gamma-ray bursts (GRBs) by considering the Lorentz violation of neutrinos, we provide a new estimate on the GRB neutrino flux with a more significant result compared to the previous constraint by the IceCube Collaboration. Among these 24 neutrino "shower" events above 60 TeV, 12 events are associated with GRBs. Such a result is compatible with the prediction from GRB fireball models. Analysis of track events provides a consistent result with the shower events to associate high energy cosmic neutrinos with GRBs under the same Lorentz violation features of neutrinos. We also make a background estimation and reveal GRBs as a significant source for the ultra-high energy IceCube neutrino events. Our work supports the Lorentz violation and -violation of neutrinos, indicating new physics beyond relativity.
基于最近通过考虑中微子的洛伦兹破缺将冰立方TeV和PeV中微子事件与伽马射线暴（GRB）联系起来，我们对GRB中微子通量进行了新的估计，与冰立方合作组之前的限制相比，结果更显著。在这24个能量高于60 TeV的中微子“簇射”事件中，有12个事件与GRB相关。这样的结果与GRB火球模型的预测相符。对径迹事件的分析提供了与簇射事件一致的结果，即在中微子相同的洛伦兹破缺特征下，将高能宇宙中微子与GRB联系起来。我们还进行了背景估计，并揭示GRB是超高能冰立方中微子事件的一个重要来源。我们的工作支持中微子的洛伦兹破缺，表明了相对论之外的新物理。
