高能宇宙线（UHECR）观测中的不确定性之一来自于用于空气簇射蒙特-卡罗（MC）模拟的强子相互作用模型。我们可以通过比较在地面上观测到的UHECR诱导的空气簇射的μ介子的测量数量与MC的预测来检验强子相互作用模型。望远镜阵列（TA）是北方半球观测美国犹他州UHECR的最大实验。它旨在通过利用表面探测器（SD）和荧光探测器阵列研究宇宙射线的能谱、质量组成和各向异性，揭示UHECR的起源。通过分析TA SD站的大倾斜阵雨信号，研究了UHE大范围空气阵雨中的μ子密度。在μ子贡献约65%的总信号的条件下，来自空气簇射的粒子数通常为1.88 ± 0.08（统计）。± 0.42（系统）倍以上的MC预测与QGSJET II-03模型的质子诱导阵雨。其他强子相互作用模型，如QGSJET II-04，也得到了同样的特征。
One of the uncertainties in ultrahigh energy cosmic ray (UHECR) observation derives from the hadronic interaction model used for air shower Monte-Carlo (MC) simulations. One may test the hadronic interaction models by comparing the measured number of muons observed at the ground from UHECR induced air showers with the MC prediction. The Telescope Array (TA) is the largest experiment in the northern hemisphere observing UHECR in Utah, USA. It aims to reveal the origin of UHECRs by studying the energy spectrum, mass composition and anisotropy of cosmic rays by utilizing an array of surface detectors (SDs) and fluorescence detectors. We studied muon densities in the UHE extensive air showers by analyzing the signal of TA SD stations for highly inclined showers. On condition that the muons contribute about 65% of the total signal, the number of particles from air showers is typically 1.88 ± 0.08 (stat.) ± 0.42 (syst.) times larger than the MC prediction with the QGSJET II-03 model for proton-induced showers. The same feature was also obtained for other hadronic interaction models, such as QGSJET II-04.
