论文摘要
空气淋浴中产生的Cherenkov光在很大程度上有助于在地面伽马射线和宇宙射线观测器中观察到的信号。然而，尚无对这种现象的描述，涵盖了淋浴轴的两个小角度和大角度的区域。为了填补这一空白，根据物理动机的参数函数进行了Cherenkov光子的角度分布的参数化。使用模拟参数使用模拟伽马射线和质子淋浴在TEV到EEV区域的能量。结果，获得了一个新的参数化，以提高以前的作品的精度。此处介绍的结果可用于重建带有成像Cherenkov望远镜的阵雨，以及用荧光探测器重建淋浴轮廓。
The Cherenkov light produced in air showers largely contributes to the signal observed in ground-based gamma-ray and cosmic-ray observatories. Yet, no description of this phenomenon is available covering both regions of small and large angles to the shower axis. To fill this gap, a parametrization of the angular distribution of Cherenkov photons is performed in terms of a physically-motivated parametric function. Model parameters are constrained using simulated gamma-ray and proton showers with energies in the TeV to EeV region. As a result, a new parametrization is obtained that improves the precision of previous works. Results presented here can be used in the reconstruction of showers with imaging Cherenkov telescopes as well as in the reconstruction of shower profiles with fluorescence detectors.
