论文摘要
通过天文学家的电报和伽马射线协调网络通函，已报道了Lhaaso的伽马射线爆发221009A的初步检测，地毯2最多251 TEV的初步检测。由于这种爆发是在红移$ z = 0.1505 $的情况下，这些光子起初似乎很可能避免在背景辐射场上配对生产并生存以达到地球上的探测器。通过推断报告的$ 0.1-1.0 $ \ gev lat Spectrum从这种爆发到更高的能量，并使用它来限制爆发的固有光谱，我们表明，尽管最近对251个TEV事件的检测，但Lhaaso检测到的18个TEV光子的生存并非不可能。如果在线性（$ n = 1 $）的情况下以能量量表$ e _ {\ rm planck} $ \，则可以解决这可以解决。 （$ n = 2 $）情况（95 \％置信度限制），其中$ e _ {\ rm planck} $是Planck Energy。这有可能是违反洛伦兹的跨司型违规行为的第一个证据。
The preliminary detections of the gamma-ray burst 221009A up to 18 TeV by LHAASO and up to 251 TeV by Carpet 2 have been reported through Astronomer's Telegrams and Gamma-ray Coordination Network circulars. Since this burst is at redshift $z=0.1505$, these photons may at first seem to have a low probability to avoid pair production off of background radiation fields and survive to reach detectors on Earth. By extrapolating the reported $0.1-1.0$\ GeV LAT spectrum from this burst to higher energies and using this to limit the intrinsic spectrum of the burst, we show that the survival of the 18 TeV photon detected by LHAASO is not unlikely with many recent extragalactic background light models, although the detection of a 251 TeV event is still very unlikely. This can be resolved if Lorentz invariance is violated at an energy scale $E_{\rm QG}< 49 E_{\rm Planck}$\ in the linear ($n=1$) case, and $E_{\rm QG}< 10^{-6}E_{\rm Planck}$\ in the quadratic ($n=2$) case (95\% confidence limits), where $E_{\rm Planck}$ is the Planck energy. This could potentially be the first evidence for subluminal Lorentz invariance violation.
