摘要:

通过模拟研究了单个EAS中横向μ子密度分布的μ子电荷比,最近的建议是测量与EAS观测相一致的可观测值。虽然强子相互作用的影响不会导致总的μ子正和μ子负的内容的显着差异,μ子密度的方位角变化的相反的电荷和μ子电荷比的方位角变化的差异似乎是非常明显的,取决于EAS入射的方向。这是由于地磁场的影响,它引起了来自扩展空气簇射的无线电发射的相关效应。

英文摘要:

The muon charge ratio of the lateral muon density distributions in single EAS is studied by simulations, in context of recent proposals to measure this observable in coincidence with EAS observations. While effects of the hadronic interaction do not lead to significant differences of the total muon plus and muon minus content, the differences of the azimuthal variation of the muon densities of opposite charges and the azimuthal variation of the muon charge ratio appear to be very much pronounced, dependent on the direction of EAS incidence. This is due to the influence of the geomagnetic field which induces related effects in radio emission from extended air showers.
