从宇宙光子衰减寻找洛伦兹不变性破坏

Searching Lorentz invariance violation from cosmic photon attenuation

Hao Li, Bo-Qiang Ma

摘要:

洛伦兹不变性破坏LIV可以改变狭义相对论预言的阈值行为,引起阈值异常,从而影响宇宙光子的传播。本文主要研究了阈值反常对河外背景光~(EBL)对宇宙光子衰减的影响,并讨论了如何从宇宙中远距离传播的甚高能量~(VHE)光子的观测中识别LIV。我们指出,大型高空空气簇射天文台(LHAASO)是目前在TeV和PeV能区工作的最灵敏的γ射线探测器阵列之一,是进行这种LIV搜索的理想设施。我们应用所提出的策略来讨论新观测到的伽马射线暴GRB 221009 A,以证明我们的建议的预测能力。

英文摘要:

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.
