论文摘要
最近发现的TEV从伽马射线爆发（GRB）提示的TEV发射暗示了该辐射分量的可能起源。我们开发了一个蒙特卡洛（MC）模拟，该模拟在内部冲击时重现了光 - 光子相互作用的运动学，包括次级伽玛射线在GRB射流中进行的配对生产过程。我们发现，GRB 190114C的子TEV观测值可以通过与子GEV光子和大量Lorentz因子$γ= 100 $相当的Baryonic Energy含量复制，并具有MS变异时间表。发现模型的中微子通量预测与Antares和IceCube设定的实验上限一致。
The recently discovered TeV emission from Gamma-Ray Bursts (GRBs) hints towards a possible hadronic origin of this radiation component. We developed a Monte Carlo (MC) simulation reproducing the kinematics of photo-hadronic interactions at internal shocks, including the pair production process that the secondary gamma rays undergo in the GRB jet. We find that sub-TeV observations of GRB 190114C can be reproduced by a baryonic energy content comparable to that in sub-GeV photons and a bulk Lorentz factor $Γ=100$, with a ms variability timescale. Neutrino flux predictions by the model are found to be consistent with experimental upper limits set by ANTARES and IceCube.
