摘要:

我们研究了广泛的空气簇射发展的依赖性的第一强子相互作用在超高能量发生在启动阶段的空气簇射级联。标准空气簇射观测值的解释取决于这些相互作用的特性。因此,目前很难从对空气簇射数据的分析中得出确定的结论,例如关于初级宇宙射线质量组成的结论。另一方面,一个已知的初级质量组成将使我们能够研究强子相互作用的质心能量远高于范围内,是可以访问的加速器测量。

英文摘要:

We study the dependence of extensive air shower development on the first hadronic interactions at ultra-high energies occurring in the startup phase of the air shower cascade. The interpretation of standard air shower observables depends on the characteristics of these interactions. Thus, it is currently difficult to draw firm conclusions for example on the primary cosmic ray mass composition from the analysis of air shower data. On the other hand, a known primary mass composition would allow us to study hadronic interactions at center of mass energies well above the range that is accessible to accelerators measurements.
