摘要
本文提出了一种新的方法来估计能量超过1.25 \times 10^{19}$eV的单个事件中宇宙射线的质量组成。它是在对实验数据和模拟结果进行联合分析的基础上提出来的，模拟结果是使用QGSJet-II.04模型对天顶角达到60度的空气阵列中阈值能量为$E_{\mu}= 1.0 \times \cos\theta$ GeV的μ介子进行模拟的。使用的数据来自雅库茨克 EAS 阵列的地面和地下闪烁探测器。发现了独立的原子核和其他原初粒子群。
Estimation of the composition of ultra-high energy cosmic rays using the muon correlation method based on Yakutsk EAS array data
In this article a new method is proposed for estimating the mass composition
of cosmic rays in individual events with energies above $1.25 \times 10^{19}$
eV. It is based on a joint analysis of experimental data and simulation results
obtained using the QGSJet-II.04 model for muons with threshold energy $E_{\mu}
= 1.0 \times \cos\theta$ GeV in air showers with zenith angles up to 60
degrees. The data from ground-based and underground scintillation detectors of
the Yakutsk EAS array were used. Separate groups of nuclei and other primary
particles were found.
