在本信中，我们研究了通过引入非弹性度测量来提升大气中微子实验对中微子质量顺序（NMO）灵敏度的潜力。我们展示了该可观测量如何提高对NMO的灵敏度以及大气中微子相关其他中微子振荡参数的精度，特别是在IceCube-Upgrade和KM3NeT-ORCA探测器中。我们的结果表明，在假设IceCube-Upgrade和KM3NeT-ORCA探测器分别运行5年和3年的场景下，包含非弹性度信息的大气中微子振荡分析有潜力将质量顺序判别能力提升数个χ²单位。
英文摘要
In this letter, we study the potential of boosting the atmospheric neutrino experiments sensitivity to the neutrino mass ordering (NMO) sensitivity by incorporating inelasticity measurements. We show how this observable improves the sensitivity to the NMO and the precision of other neutrino oscillation parameters relevant to atmospheric neutrinos, specifically in the IceCube-Upgrade and KM3NeT-ORCA detectors. Our results indicate that an oscillation analysis of atmospheric neutrinos including inelasticity information has the potential to enhance the ordering discrimination by several units of $χ^2$ in the assumed scenario of 5 and 3 years of running of IceCube-Upgrade and KM3NeT-ORCA detectors, respectively.
