A A Lagutin, R I Raikin, T L Serebryakova

摘要:

在考虑Landau-Pomeranchuk-Migdal效应和地磁场效应的情况下,在较宽的一次能量范围($10^{14}÷10^{22}$ ~eV)内研究了核和光子引发的空气簇射的标度特性.结果表明,直到最高能量,电子分量的横向分布不变性以及簇射年龄与均方根半径之间的普遍依赖性都存在。详细讨论了簇射普适性对再分析、交叉检验和验证不同实验结果以及降低强子模型不确定性影响的意义。

英文摘要:

Scaling properties of nuclei- and photon-initiated air showers are examined in wide primary energy range ($10^{14}÷10^{22}$~eV) taking into account Landau-Pomeranchuk-Migdal and geomagnetic field effects. It is shown that the invariance in lateral distribution and also the universal dependence between shower age and root mean square radius of electron component exist up to the highest energies. The implications of shower universality for reanalysis, cross-checking and validation of the results of different experiments together with decreasing of the influence of hadronic model uncertainties are discussed in detail.
