论文摘要
质量组成对于理解超高能量宇宙射线的起源很重要。然而，由于空气淋浴模拟中采用的强大相互作用模型的明显不确定性，空气淋浴实验中对质量组成的解释具有挑战性。特定的不确定性来源是衍射解离，因为其在加速器实验中的测量表现出显着的系统不确定性。在这项研究中，我们估计了$ \ langle x _ {\ rm max} \ rangle $中的不确定性，从爱丽丝实验的衍射解离的不确定性中。整个空气淋浴的最大不确定性大小估计为$^{+4.0} _ { - 5.6} \ Mathrm {g/cm^2} $，对于$ 10^{17} $ ev质子引起的空中淋浴，这在$ \ \ langle x _ _ {\ mmax的情况下不可忽略不计。
Mass composition is important for understanding the origin of ultra-high-energy cosmic rays. However, interpretation of mass composition from air shower experiments is challenging, owing to significant uncertainty in hadronic interaction models adopted in air shower simulation. A particular source of uncertainty is diffractive dissociation, as its measurements in accelerator experiments demonstrated significant systematic uncertainty. In this research, we estimate the uncertainty in $\langle X_{\rm max}\rangle$ from the uncertainty of the measurement of diffractive dissociation by the ALICE experiment. The maximum uncertainty size of the entire air shower was estimated to be $^{+4.0}_{-5.6} \mathrm{g/cm^2}$ for air showers induced by $10^{17}$ eV proton, which is not negligible in the uncertainty of $\langle X_{\rm max}\rangle$ predictions.
