摘要:

能量超过~ 10^18 eV的超高能宇宙射线提供了一个独特的窗口,可以研究能量远高于最大的人造加速器所能达到的能量的强子相互作用。我们认为,在这些能量弦渗透可能会发生,并发挥重要作用的描述诱导广泛的空气簇射通过增强奇异和重子生产。这导致级联的μ介子含量的显着增加,与最近在UHECR实验收集的数据一致。在这项工作中,强子相互作用中的弦渗流的影响实现了EAS代码和几个淋浴可观的影响进行了评估和讨论。

英文摘要:

Ultra High Energy Cosmic Rays with energies above ~ 10^18 eV provide an unique window to study hadronic interactions at energies well above those achieved in the largest man-made accelerators. We argue that at those energies string percolation may occur and play an important role on the description of the induced Extensive Air Showers by enhancing strangeness and baryon production. This leads to a significant increase of the muon content of the cascade in agreement with recent data collected at UHECR experiments. In this work, the effects of string percolation in hadronic interactions are implemented in an EAS code and their impact on several shower observables is evaluated and discussed.
