摘要:

在本文中,我们介绍了一种新的多参数技术,试图同时解决的问题的组成确定和强子相互作用的不确定性。采用模拟现实世界的探测器在其计划的操作条件下,并忽略系统学,我们可以评估,目前的技术应该能够确定的组成的二元混合物的p和Fe的统计置信度的百分之几,在某种程度上,是独立的假设强子相互作用模型。此外,结合实际数据的工具开发和介绍这里应该给在该地区目前使用的各种强子相互作用模型的可靠性的指示。我们的研究中心在脚踝的区域,那里的组成进行了关键的天体物理信息,并使用两个主要参数:在600米处的介子的数量从簇射轴和簇射最大的深度从计划的介子计数器和AMIGA和HEAT俄歇增强的高海拔荧光望远镜的混合操作获得。

英文摘要:

In this paper we introduce a new multiparametric technique that attempts to tackle simultaneously the problems of composition determination and hadronic interaction uncertainty. Employing simulations of a real world detector under its planned operational conditions, and disregarding systematics, we can asses that the present technique should be able to determine the composition of a binary mixture of p and Fe with a statistical confidence of few percent, in a way that is independent of the assumed hadronic interaction model. Moreover, the combination of real data with the tools developed and presented here should give an indication of the reliability of the various hadronic interaction models in current use in the area. We center our study in the region of the ankle, where composition carries critical astrophysical information, and use two main parameters: the number of muons at 600 m from the shower axis and the depth of the shower maximum obtained from the hybrid operation of the planned muon counters and high elevation fluorescence telescopes of the AMIGA and HEAT Auger enhancements.
