We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables the detection and reconstruction of neutrinos produced by the interaction of cosmic rays in Earth's atmosphere at energies as low as ∼5 GeV. That energy threshold permits measurements of muon neutrino disappearance, over a range of baselines up to the diameter of the Earth, probing the same range of L/E_{ν} as long-baseline experiments but with substantially higher-energy neutrinos. This analysis uses neutrinos from the full sky with reconstructed energies from 5.6 to 56 GeV. We measure Δm_{32}^{2}=2.31_{-0.13}^{+0.11}×10^{-3} eV^{2} and sin^{2}θ_{23}=0.51_{-0.09}^{+0.07}, assuming normal neutrino mass ordering. These results are consistent with, and of similar precision to, those from accelerator- and reactor-based experiments.
我们利用冰立方中微子天文台三年的数据对大气中微子振荡参数进行了测量。冰立方中心的深地核心填充阵列能够探测和重建宇宙射线与地球大气相互作用产生的能量低至约5 GeV的中微子。该能量阈值允许在长达地球直径的一系列基线范围内测量μ子中微子消失情况，探测与长基线实验相同的L/Eν范围，但使用的中微子能量要高得多。该分析使用了来自全天空、重建能量在5.6至56 GeV之间的中微子。假设中微子质量为正常排序，我们测量得到Δm₃₂² = 2.31₋₀.₁₃⁺₀.₁₁×10⁻³ eV²，sin²θ₂₃ = 0.51₋₀.₀₉⁺₀.₀₇。这些结果与基于加速器和反应堆的实验结果一致，且精度相近。
