高能中微子在物质中传播的完全预言

Complete predictions for high-energy neutrino propagation in matter

Alfonso Garcia, Rhorry Gauld, Aart Heijboer, Juan Rojo

摘要:

我们提出了预测的相互作用的高能中微子与物质,因为它们通过地球传播到大体积探测器。我们的结果是基于国家的最先进的计算的高能中微子物质相互作用截面,我们已经实现了在HEDIS模块的GENIE。除了主要的相互作用过程,夸克和胶子的深度非弹性散射,我们还包括相关的次主导通道:核子光子场的弹性散射,原子核光子场的相干散射,以及原子电子通过共振的散射。我们对中微子衰减率的预测是由一个新的软件包NuPropEarth提供的。我们量化了我们的结果对截面模型的依赖性,包括核修正,入射角和光谱指数,并将它们与其他公开可用的工具进行比较。

英文摘要:

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.
