高能中微子与宇宙射线

High Energy Neutrinos and Cosmic Rays

Guenter Sigl

摘要:

这是一个关于我们对宇宙辐射的起源和性质的理解的实验和理论现状的系列讲座的总结。特别关注的是~10^17 eV以上的超高能宇宙辐射,包括次级中性粒子,特别是中微子。最重要的悬而未决的问题与这些粒子的质量组成和天空分布以及它们的来源的位置和性质有关。来自地外来源的GeV及以上能量的高能中微子尚未被探测到,实验上限开始对极高能宇宙射线的来源和加速机制产生强烈的限制。

英文摘要:

This is a summary of a series of lectures on the current experimental and theoretical status of our understanding of origin and nature of cosmic radiation. Specific focus is put on ultra-high energy cosmic radiation above ~10^17 eV, including secondary neutral particles and in particular neutrinos. The most important open questions are related to the mass composition and sky distributions of these particles as well as on the location and nature of their sources. High energy neutrinos at GeV energies and above from extra-terrestrial sources have not yet been detected and experimental upper limits start to put strong contraints on the sources and the acceleration mechanism of very high energy cosmic rays.
