论文摘要
下一个中微子实验将在我们对中微子部门的肌酸物理物理学的理解中的限制提高到比当前最新的高能中微子实验Icecube高的数量级。这些实验将使用中微子来告诉我们宇宙中最极端的环境，同时利用这些极端环境作为可预见的最高能量的中微子特性的探针：$ e \ sim10^9 $ gev。在这些能量下，中微子很容易在地球上吸收。假设使用各向同性分布，通过查看通量如何随着地球的角度而变化，我们表明，可以在$ \ sim20 \％$ lack（假设Wilks'theorem'theorem）$ n _ _ _ _ _ {\ rm everts $ n _ {\ rm everts} \ sim100 $ everts提取$ n $ n $ cross cross部分，以$ \ sim20 \％$级别（$1σ$级别（$1σ$））。
Next generation neutrino experiments will push the limits in our understanding of astroparticle physics in the neutrino sector to energies orders of magnitude higher than the current state-of-the-art high-energy neutrino experiment, IceCube. These experiments will use neutrinos to tell us about the most extreme environments in the universe, while simultaneously leveraging these extreme environments as probes of neutrino properties at the highest energies accessible in the foreseeable future: $E\sim10^9$ GeV. At these energies neutrinos are readily absorbed in the Earth. Assuming an isotropic distribution, by looking at how the flux varies as a function of angle through the Earth, we show that it is possible to extract the $ν_τ$-$N$ cross section with precision at the $\sim20\%$ level ($1σ$ assuming Wilks' theorem) given $N_{\rm events}\sim100$ events.
