Because of the high energies and long distances to the sources, astrophysical observations provide a unique opportunity to test possible signatures of Lorentz invariance violation (LIV). Superluminal LIV enables the decay of photons at high energy. The high altitude water Cherenkov (HAWC) observatory is among the most sensitive gamma-ray instruments currently operating above 10 TeV. HAWC finds evidence of 100 TeV photon emission from at least four astrophysical sources. These observations exclude, for the strongest of the limits set, the LIV energy scale to 2.2×10^{31} eV, over 1800 times the Planck energy and an improvement of 1 to 2 orders of magnitude over previous limits.

HAWC对100 TeV以上的伽玛射线观察到的洛伦兹不变性约束。

由于能量高且距离源很远，天体物理观测提供了独特的机会来测试可能的洛伦兹不变性违规（LIV）特征。超腔LIV使高能光子衰减。高海拔水切伦科夫（HAWC）天文台是目前运行在10 TeV以上的最敏感的伽马射线仪器之一。HAWC从至少四个天体物理学来源发现了100 TeV光子发射的证据。这些观察结果排除了设置的最强限制，即LIV能量标度达到2.2×10 ^ {31} eV，是普朗克能量的1800倍以上，并且比以前的限制提高了1到2个数量级。
