论文摘要
大型高空空气淋浴天文台〜（Lhaaso）最近报道了从蟹状星云中发现的伽马射线排放，其能量高达$ 1.1〜 \ textrm {pev} $。利用逆孔普顿电子缺乏真空cherenkov效应，我们在电子的分散关系中提高了以前的界限到线性阶lorentz不变性违规（LV）的范围，提高了$ 10^{4} $ timess。我们表明，LV对电子的效应受到严格限制，与某些量子重力〜（QG）（例如弦/D-Brane启发的时空泡沫）所预期的某些类型的LV兼容。我们认为，这种模型得到了lhaaso观测值的蟹状星云约束，以及迄今为止光子的各种LV现象学。
The Large High Altitude Air Shower Observatory~(LHAASO) recently reported the detection of gamma-ray emissions with energies up to $1.1~\textrm{PeV}$ from the Crab Nebula. Using the absence of vacuum Cherenkov effect by inverse-Compton electrons, we improve previous bounds to linear-order Lorentz invariance violation (LV) in the dispersion relations of electrons by $10^{4}$ times. We show that the LV effect on electrons is severely constrained, compatible with certain type of LV as expected by some models of quantum gravity~(QG), such as the string/D-brane inspired space-time foam. We argue that such models are supported by the Crab Nebula constraints from the LHAASO observations, as well as various LV phenomenologies for photons to date.
