论文摘要
超高能量（UHE）中微子，具有EEV尺度的能量，随身携带了对天体物理学和粒子物理学中基本的开放问题的独特见解。五十年来，他们已经逃避了发现，但由于目前正在开发的新UHE中微子望远镜，可能还没有更长的时间。我们通过在未来10 - 20年内发现了UHE中微子的弥漫性通量的最先进的预测来利用这一即将到来的机会。根据设计，我们的预测是基于理论和实验经常被掩盖的细微差别。我们将它们装备到计划的IceCube-gen2检测器的无线电阵列。我们发现令人鼓舞的前景：即使在保守分析的选择下，文献中可用的大多数基准中微子通量模型也可能会在检测器暴露的10年内发现 - 许多人早日 - 可能会彼此区分。我们的结果证明了下一代中微子望远镜的变革潜力。
Ultra-high-energy (UHE) neutrinos, with EeV-scale energies, carry with them unique insight into fundamental open questions in astrophysics and particle physics. For fifty years, they have evaded discovery, but maybe not for much longer, thanks to new UHE neutrino telescopes, presently under development. We capitalize on this upcoming opportunity by producing state-of-the-art forecasts of the discovery of a diffuse flux of UHE neutrinos in the next 10-20 years. By design, our forecasts are anchored in often-overlooked nuance from theory and experiment; we gear them to the radio array of the planned IceCube-Gen2 detector. We find encouraging prospects: even under conservative analysis choices, most benchmark UHE neutrino flux models available in the literature may be discovered within 10 years of detector exposure -- many sooner -- and may be distinguished from each other. Our results validate the transformative potential of next-generation UHE neutrino telescopes.
