摘要:

中微子射线照相术可能为研究地球的深层结构提供另一种工具。虽然这些测量不能分辨精细的密度层特征,但是可以获得的信息是独立的,并且是对更常规的地震研究的补充。本文的目的是评估如何以及核和地幔的平均密度可以通过大气中微子照相重建。我们发现,在水下千米^3中微子望远镜10年的数据采集中,地幔的灵敏度约为2%,地核的灵敏度约为5%。这个结果没有考虑到与实验装置细节相关的系统学。

英文摘要:

Neutrino radiography may provide an alternative tool to study the very deep structures of the Earth. Though these measurements are unable to resolve the fine density layer features, nevertheless the information which can be obtained are independent and complementary to the more conventional seismic studies. The aim of this paper is to assess how well the core and mantle averaged densities can be reconstructed through atmospheric neutrino radiography. We find that about a 2% sensitivity for the mantle and 5% for the core could be achieved for a ten year data taking at an underwater km^3 Neutrino Telescope. This result does not take into account systematics related to the details of the experimental apparatus.
