中微子在地球中的传播

On the propagation of neutrinos through the Earth

M. de Jong

摘要:

地球通常被用作深地下和深海中微子望远镜操作的天然过滤器。通过选择指向上方的事件,可以有效地抑制探测器上方地球大气中宇宙射线相互作用产生的μ子背景。幸存的中微子在被探测到之前穿越了地球的很大一部分。通常认为,探测到的中微子以直线穿过地球,而不会损失能量。首次研究了中微子在地球中的传播,包括带电电流和中性电流相互作用的影响。结果表明,这将导致中微子的可探测通量的增加。

英文摘要:

The Earth is commonly used as a natural filter for the operation of deep-underground and deep-sea neutrino telescopes. By selecting events pointing in upward directions, the background of muons produced by interactions of cosmic rays in the Earth' atmosphere above the detector can effectively be suppressed. The surviving neutrinos traversed a large part of the Earth before being detected. It is commonly assumed that the detected neutrinos go in a straight line through the Earth without loosing energy. A first study has been made of the propagation of neutrinos through the Earth which includes the effects of the charged-current as well as neutral-current interactions. It is found that this leads to an increase of the detectable flux of neutrinos.
