AI总结：

本文研究了RNO-G、GRAND和IceCube-gen2射电阵列等未来中微子射电望远镜对质量在10^7至10^15 GeV的重衰变暗物质的探测灵敏度，预测了基于宇宙原初中微子和新生脉冲星中微子观测的暗物质寿命保守限制，结果表明这些限制与多信使分析高度互补。

摘要：

在未来几十年中，EeV能段的超高能中微子有望被下一代中微子望远镜探测到。尽管这些望远镜的主要目标是观测宇宙原初中微子并深入了解极端天体物理环境，它们也能间接探测暗物质的性质。本文研究了即将投入运行的中微子射电望远镜——如RNO-G、GRAND和IceCube-gen2射电阵列——对衰变暗物质情形的预期灵敏度。我们考察了不同的暗物质衰变道和质量范围，从10^7 GeV到10^15 GeV。通过假设观测到宇宙原初中微子或新生脉冲星中微子，我们预测了对重暗物质粒子寿命的保守限制。我们发现这些限制与以往的多信使分析结果相比具有竞争力，并且高度互补。

英文摘要：

In the next decades, ultra-high-energy neutrinos in the EeV energy range will be potentially detected by next-generation neutrino telescopes. Although their primary goals are to observe cosmogenic neutrinos and to gain insight into extreme astrophysical environments, they can also indirectly probe the nature of dark matter. In this paper, we study the projected sensitivity of up-coming neutrino radio telescopes, such as RNO-G, GRAND and IceCube-gen2 radio array, to decaying dark matter scenarios. We investigate different dark matter decaying channels and masses, from $10^7$ to $10^{15}$ GeV. By assuming the observation of cosmogenic or newborn pulsar neutrinos, we forecast conservative constraints on the lifetime of heavy dark matter particles. We find that these limits are competitive with and highly complementary to previous multi-messenger analyses.
