论文摘要
我们提出了对高能中微子与物质相互作用的预测,因为它们通过地球传播到大容量探测器时。我们的结果基于对高能中微子相互作用横截面的最新计算,我们已经在Genie的Hedis模块中实现了。除了主要的相互作用过程,深度非弹性散射从夸克和胶子上散射,我们还包括相关的亚较大通道:(in)弹性散射核子的光子场,连贯的核片段散射,以及通过Glashow resonance在原子电子上散射的光子散射。我们对中微子衰减率的预测由新软件包Nupropearth提供。我们量化了结果对横截面模型的依赖性,包括核校正,入射角和光谱指数,并将其与其他公开可用工具进行比较。
We present predictions for the interactions of energetic neutrinos with matter as they propagate through Earth towards large-volume detectors. Our results are based on state-of-the-art calculations of the high-energy neutrino-matter interaction cross-sections, which we have implemented in the HEDIS module of GENIE. In addition to the dominant interaction process, deep inelastic scattering off quarks and gluons, we include the relevant subdominant channels: (in)elastic scattering off the photon field of nucleons, coherent scattering off the photon field of nuclei, as well as the scattering on atomic electrons via the Glashow resonance. Our predictions for the neutrino attenuation rates are provided by a new software package, NuPropEarth. We quantify the dependence of our results on the cross-section model, including nuclear corrections, the incidence angle, and the spectral index, and compare them with other publicly available tools.
