Raul Ribeiro Prado, Ruben Conceição, Mário Pimenta, Vitor de Souza

摘要:

在本文中,我们分析了$10^{18.4}$和$10^{19.6}$ eV之间的空气簇射的μ子含量的能量演化,以便能够从未来μ子测量的数量确定最可能的质量组成方案。基于Heitler-Matthews模型和空气簇射的蒙特卡罗模拟,研究了μ子数的能量和初始质量演化。提出并验证了一个描述μ子数分布一阶矩和二阶矩演化的简单模型。一种分析方法的基础上,该模型的预测和数据之间的比较,以区分一组组成的情况下,提出和模拟测试。它示出的组合物的情况下,可以潜在的歧视所施加的条件下的方法。所提出的分析的鉴别能力是稳定的系统变化的绝对数量的μ子从模型预测和重建的能量的规模。

英文摘要:

In this paper we analyze the energy evolution of the muon content of air showers between $10^{18.4}$ and $10^{19.6}$ eV to be able to determine the most likely mass composition scenario from future number of muons measurements. The energy and primary mass evolution of the number of muons is studied based on the Heitler-Matthews model and Monte Carlo simulation of the air shower. A simple model to describe the evolution of the first and second moments of number of muons distributions is proposed and validated. An analysis approach based on the comparison between this model's predictions and data to discriminate among a set of composition scenarios is presented and tested with simulations. It is shown that the composition scenarios can be potentially discriminated under the conditions imposed by the method. The discrimination power of the proposed analysis is stable under systematic changes of the absolute number of muons from model predictions and on the scale of the reconstructed energy.
