论文摘要
在这项研究中，研究了探索超高能颗粒宇宙射线相互作用的模拟研究的必要性。通过使用Air Showers Simulation Aires System（版本19.04.00），模拟了不同的HADRONIC交互模型，例如（Sibyll，QGSJET和EPOS）。同样，通过估计横向分布函数（LDF）来计算广泛的空气淋浴的带电颗粒密度（EAS）。此外，考虑了它们的主要能量效应，以及在能量范围内产生的电荷颗粒的主要能量效应（10^17-10^19）EV，对两个主要颗粒（质子和铁核）进行了LDF模拟。在极高的能量（10^17、10^18和10^19）EV时，通过使用Sigmoidal函数（Logistic模型）拟合EAS的横向分布曲线，获得了新的参数作为主要能量的函数。结果的比较表明，使用Sigmoidal函数从参数化的LDF获得的值与Agasa EAS观测值的实验结果之间的良好一致性，以及铁核以及铁核的实验结果，以及（电子效应）对的产生（电子）对和带电的MUONS二级颗粒在高能量的高能量，大约10^19 eV和（Theta = 0 = 0）。
In this study, the necessity of the simulation study for exploring the interactions of ultra-high energy particles cosmic rays was examined. Different hadronic interaction models such as (SIBYLL, QGSJET, and EPOS) were simulated by using air showers simulation AIRES system (version 19.04.00). Also, the charged particle density of Extensive Air Showers (EAS) was calculated by estimating the lateral distribution function (LDF). Moreover, the LDF simulation of the two primary particles (proton and iron nuclei) was performed, taking into account their primary energies effect and the zenith angle of charged particles that produced in the EAS, within the energy range (10^17-10^19) eV. At extremely high energies (10^17, 10^18, and 10^19) eV, new parameters as a function of the primary energy were obtained by fitting the lateral distribution curves of EAS using Sigmoidal function (Logistic model). Comparison of the results showed a good agreement between the values obtained from the parameterized LDF using Sigmoidal function with experimental results by AGASA EAS observatory for the primaries proton as well iron nuclei, with the production of (electron positron) pair and the charged muons secondary particles at high energy about 10^19 eV and (theta = 0 degree).
