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 chi(2) in the assumed scenario of five and three years of running of IceCube-Upgrade and KM3NeT-ORCA detectors, respectively.
