高能天体物理学与中微子望远镜

High-Energy Astrophysics with Neutrino Telescopes

T. Chiarusi, M. Spurio

摘要:

中微子天体物理学为宇宙研究提供了新的视角:高能中微子,由我们银河系和宇宙中最具活力的现象产生,携带关于光子的宇宙补充(如果不是唯一的)信息。虽然中微子的小相互作用截面使它们能够来自天体的核心,但这也是一个缺点,因为它们的探测需要很大的目标质量。这就是为什么把巨大的宇宙中微子探测器放在自然位置,比如深海或冰下的地方是很方便的。为了应对这种极端恶劣的环境条件,正在开发新的前沿技术。这项工作的目的是审查高能量中微子天体物理学的动机,目前的实验结果和水下/冰切伦科夫实验中使用的技术,特别侧重于在地中海建造一个公里3级探测器的努力。

英文摘要:

Neutrino astrophysics offers new perspectives on the Universe investigation: high energy neutrinos, produced by the most energetic phenomena in our Galaxy and in the Universe, carry complementary (if not exclusive) information about the cosmos with respect to photons. While the small interaction cross section of neutrinos allows them to come from the core of astrophysical objects, it is also a drawback, as their detection requires a large target mass. This is why it is convenient put huge cosmic neutrino detectors in natural locations, like deep underwater or under-ice sites. In order to supply for such extremely hostile environmental conditions, new frontiers technologies are under development. The aim of this work is to review the motivations for high energy neutrino astrophysics, the present status of experimental results and the technologies used in underwater/ice Cherenkov experiments, with a special focus on the efforts for the construction of a km3 scale detector in the Mediterranean Sea.
