论文摘要

我们使用来自MINOS和MINOS+实验的所有数据报告了中微子振荡参数的最终测量。这些数据是使用目标产生$ν_{MU} $和$ \ OVERLINE {ν_μmebems和60.75 kt $ \ cdot $ yr yr yr yr暴露于大气中性中子的$ν_{mu} $的总暴露$ 23.76 \ times 10^{20} $质子。 $ν_μ$消失的测量以及近距离检测器之间的$ν_e$事件的出现产生$ |Δm^2_ {32} | = 2.40^{+0.08} _ { - 0.09}〜（2.45^ $ \ sin^2θ_{23} = 0.43^{+0.20} _ { - 0.04}〜（0.42^{+0.07} _ { - 0.03}）$ 68％c.l.对于普通（倒置）层次结构。

We report the final measurement of the neutrino oscillation parameters $Δm^2_{32}$ and $\sin^2θ_{23}$ using all data from the MINOS and MINOS+ experiments. These data were collected using a total exposure of $23.76 \times 10^{20}$ protons on target producing $ν_{mu}$ and $\overline{ν_μ}$ beams and 60.75 kt$\cdot$yr exposure to atmospheric neutrinos. The measurement of the disappearance of $ν_μ$ and the appearance of $ν_e$ events between the Near and Far detectors yields $|Δm^2_{32}|=2.40^{+0.08}_{-0.09}~(2.45^{+0.07}_{-0.08}) \times 10^{-3}$ eV$^2$ and $\sin^2θ_{23} = 0.43^{+0.20}_{-0.04} ~(0.42^{+0.07}_{-0.03})$ at 68% C.L. for Normal (Inverted) Hierarchy.
