论文摘要
洛伦兹违规〜（LIV）可以改变特殊相对论预测的阈值行为，并导致影响宇宙光子传播的阈值异常。在这项工作中，我们专注于阈值异常对宇宙光子衰减的效果，并通过外层次背景光（EBL）讨论如何从宇宙中长距离传播的非常高能量（VHE）光子的观察结果中识别LIV。我们指出，大型高空空气淋浴天文台（Lhaaso）是当前在TEV和PEV Energies运行的最敏感的伽马射线检测器阵列之一，是进行此类LIV搜索的理想设施。我们采用拟议的策略来讨论新观察到的伽马射线爆发GRB 221009a，以证明我们的建议的预测能力。
Lorentz invariance violation~(LIV) can change the threshold behavior predicted by special relativity and cause threshold anomalies which affect the propagation of cosmic photons. In this work, we focus on the threshold anomaly effect on cosmic photon attenuations by extragalactic background light~(EBL) and discuss how to identify LIV from observations of very high energy~(VHE) photons propagated from long distance in the universe. We point out that the Large High Altitude Air Shower Observatory~(LHAASO), one of the most sensitive gamma-ray detector arrays currently operating at TeV and PeV energies, is an ideal facility for performing such LIV searching. We apply the proposed strategy to discuss the newly observed gamma-ray burst GRB 221009A to demonstrate the predictive ability of our suggestions.
