The paper aims to explore the asymmetry of the muon content of non-vertical and very high-energy Monte Carlo showers due to the influence of Earth’s geomagnetic field. Simulations have shown that the geomagnetic field modifies the trajectories of muons in a shower producing a polar asymmetry in the density/number of positive and negative muons in the shower front plane. The asymmetry is quantified by a transverse separation between the positive and negative muons barycentric positions through opposite quadrants across the shower core. The dependence of this transverse muon barycenter separation (TMBS) on polar position shows a clear maximum at a position that is correlated with the primary composition and geomagnetic activities. It is noticed that the maximum TMBS parameter exhibits sensitivity to any transient weakening of Earth’s magnetic shield caused by geomagnetic storm originated from bursting solar processes. Obtained simulation results are quite important to design any possible new experiment based on these features of muons in extensive air showers.

本文旨在探讨由于地球地磁场的影响，非垂直和超高能蒙特卡洛阵雨的μ子含量的不对称性。仿真表明，地磁场改变了淋浴器中的μ子的轨迹，从而在淋浴器前平面中的正负子的密度/数量上产生了极性不对称性。不对称性是通过穿过淋浴芯的相对象限，在正和负μ子重心位置之间的横向间隔来量化的。该横向μ子重心分离（TMBS）对极性位置的依赖性在与主要成分和地磁活动相关的位置上显示出明显的最大值。值得注意的是，最大TMBS参数对由爆发的太阳过程引起的地磁风暴引起的地球磁屏蔽层的任何瞬态弱化表现出敏感性。获得的模拟结果对于基于大型风淋中的μ子的这些特征设计任何可能的新实验非常重要。
