Abstract

The two most powerful extensive air showers (EAS) with energies of about 10²⁰ eV, registered at the Yakutsk EAS array during the entire observation period of 1974–2024, are considered. Both showers hit the array near the center and triggered all surface detectors and underground muon detectors with a threshold energy of E_μ = 1.0 × cos θ GeV. These events have an abnormally high fraction of muons, which is beyond current model predictions. This may change our understanding of hadron interactions at ultra-high energy, but there is also a possibility that these showers were initiated by some exotic primary particles.

雅库茨克广泛空气阵雨阵列探测到的巨大大气阵雨

本文考虑了1974-2024年整个观测期间在雅库茨克EAS阵列记录的两个能量约为1020 eV的最强大的广泛空气阵雨（EAS）。两个阵雨都击中了靠近中心的阵列，触发了所有地面探测器和地下μ子探测器，阈值能量为Eμ = 1.0 × cos θ GeV。这些事件具有异常高的μ子比例，这超出了当前模型的预测。这可能会改变我们对超高能量强子相互作用的理解，但也有可能这些阵雨是由一些奇异的初级粒子引发的。
