与Macro和核子能量有关的宇宙介子温度关系研究
Recherche De Correlations Temporelles Des Muons Cosmiques Avec Macro Et Perte D'Energie Des Nuclearites
摘要：
论文的第一部分回顾了在格兰萨索地下实验室进行的大型宏观实验的主要特点。然后描述了实验测量的大气μ子以及获得和分析大样本宇宙μ子的选择标准。用两种互补的方法分析了巨μ子的时间序列：搜索μ子事件爆发的发生和搜索μ子时间分布中的周期性。在第一种情况下使用扫描统计方法，在第二种情况下使用Lomb-Scargle光谱分析。这两种技术完成了早期用“折叠”方法进行的分析。证实了季节变化是占主导地位的周期变化，也证实了太阳日调制和恒星调制。一个单独的研究涉及的假设Nuclearites在不同的材料和探测器的能量损失的分析，其重要性进行的搜索的MACRO和SLIM实验进行了讨论。
英文摘要：
The first parts of the thesis recalls the main features of the large MACRO experiment at the underground Gran Sasso Laboratory. It then describes the atmospheric muons measured by the experiment and the selection criteria to obtain and analyze a large sample of cosmic muons. The time series of MACRO muons was analyzed with two complementary approaches: search for the occurrence of bursts of muon events and search for periodicities in the muon time distribution. The Scan Statistics method was used in the first case and the Lomb-Scargle spectral analysis in the second case. The two techniques complete early analyses performed with "folding" methods. It is confirmed that the seasonal variation is the dominant periodic variation, and one also confirms the solar diurnal and sidereal modulations. A separate study concerns the analysis of the energy losses of the hypothetical Nuclearites in different materials and detectors; their importance for the searches performed by the MACRO and the SLIM experiments is discussed.
