论文摘要
地球通常用作天然过滤器，用于在地下和深海中微子望远镜的深处运行。通过选择指向向上方向的事件，可以有效地抑制通过探测器上方地球大气中宇宙射线相互作用产生的兆子的背景。幸存的中微子在被发现之前横穿了地球的大部分。通常假定检测到的中微子在直线上穿过地球而不会失去能量。已经对中微子在地球中传播的第一项研究进行了研究，其中包括带电的电流和中性流动相互作用的影响。发现这导致中微子可检测到的通量增加。
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.
