QCD动力学和一个超高能天体物理中微子流对高能中微子数据描述的意义

Implications of the QCD dynamics and a Super-Glashow astrophysical neutrino flux on the description of ultrahigh energy neutrino data

摘要:

中微子望远镜中观测到的事件数量取决于地球中的中微子通量,它们穿过地球时的吸收以及它们在探测器中的相互作用。本文研究了高能QCD动力学对中微子在地球中传播过程中平均非弹性的能量依赖性和吸收几率的角度依赖性的影响,以及对入射中微子通量性质的影响。此外,在冰立方和冰立方-Gen 2的事件的数量估计考虑不同的情况下的QCD动力学,并假设存在一个假设的超磁共振通量,峰值以上的能量磁共振。

英文摘要:

The number of events observed in neutrino telescopes depends on the neutrino fluxes in the Earth, their absorption while crossing the Earth and their interaction in the detector. In this paper, we investigate the impact of the QCD dynamics at high energies on the energy dependence of the average inelasticity and angular dependence of the absorption probability during the neutrino propagation through the Earth, as well in the determination of the properties of the incident astrophysical neutrino flux. Moreover, the number of events at the IceCube and IceCube - Gen2 are estimated considering different scenarios for the QCD dynamics and assuming the presence of a hypothetical Super - Glashow flux, which peaks for energies above the Glashow resonance.
