AI中文摘要：
超高能（UHE）中微子的能量高于$100\text{PeV}$，是基础物理的强大探针，为检验和约束标准模型之外的模型提供了独特机会。核心挑战在于实现对其味成分的灵敏度，味成分编码了源处的产生机制以及传播过程中潜在新物理的信息。我们首次提出一项三项技术策略，利用规划中及现有实验的互补优势来测量超高能中微子的味成分。该方法整合了冰内无线电探测（ARA、ARIANNA、RNO-G、IceCube-Gen2无线电阵列）、地球掠射（TAMBO、POEMMA、Trinity、AUGER、GRAND200k）以及冰内光学切伦科夫探测器（IceCube-Gen2光学阵列）。我们证明该方法有望实现对超高能中微子味的前所未有的灵敏度，可用于探测从TeV到EeV能量范围内源处依赖能量的中微子味转变。因此，本文强调了协调的多技术项目在推进高能与超高能中微子天体物理学方面的发现潜力。
英文摘要：
Ultra-high-energy (UHE) neutrinos, with energies above $100\,\mathrm{PeV}$, are powerful probes of fundamental physics, offering unique opportunities to test and constrain models beyond the Standard Model. A central challenge is achieving sensitivity to their flavor composition, which encodes information about production mechanisms at the source as well as potential new physics during propagation. We propose, for the first time, a three-technology strategy to measure the flavor composition of UHE neutrinos by leveraging the complementary strengths of planned and existing experiments. This approach integrates in-ice radio (ARA, ARIANNA, RNO-G, the IceCube-Gen2 radio array), Earth-skimming (TAMBO, POEMMA, Trinity, AUGER, GRAND200k), and in-ice optical Cherenkov detectors (the IceCube-Gen2 optical array). We demonstrate the potential to achieve unprecedented sensitivity to UHE neutrino flavors. The method can be used to probe an energy-dependent neutrino flavor transition at the source across energies ranging from TeV to EeV. As such, this article highlights the discovery potential of a coordinated, multi-technology program for advancing both high-energy and ultra-high-energy neutrino astrophysics.
