论文摘要
在这封信中，将灰色盘和核心模型组合在一起，旨在解释在地球大气中最高能量颗粒相互作用中观察到的不同意外特征。特别是，假设超高能量宇宙射线光谱由几个具有不同的注射光谱和最大能量截止的质子产生的质子主导，则可以解释观察到的$ x _ {\ rm max} $和$n_μ$的分布和$n_μ$。这种异源场景与其他相关观察的依从性是能量谱中的脚踏区域，$ x _ {\ rm max} $与事件的事件相关性与地面上检测到的信号之间的事件相关性，到目前为止，迄今为止无法检测到的uhe中性或光子的检测，也已经进行了简要讨论。如果得到确认，这种情况将极大地改变对UHECR主要组成的当前理解，从而改变其来源的特征。
In this letter, the Grey-Disk and the Core-Corona models are combined in a scenario that aims to explain different unexpected features observed in the interactions of the highest energy particles in the Earth's atmosphere. In particular, the observed distributions of $X_{\rm max}$ and $N_μ$ are explained, assuming that the ultra-high-energy cosmic ray spectrum is dominated by protons produced by a few extra-galactic sources with different injection spectra and maximum energy cutoffs. The compliance of this heterodox scenario with other relevant observations as the instep region in the energy spectrum, the event-by-event correlations between $X_{\rm max}$ and the detected signal at the ground and the absence of detection, so far, of UHE neutrinos or photons, are also briefly discussed. If confirmed, such a scenario would dramatically change the present understanding of the UHECR primary composition and, thus, the characteristics of their sources.
